[Scilab-users] Spam in Scilab Forge

[Nikolay Strelkov]

Dear Scilab Forge admins!

It seems that the Scilab Forge site suffers from spam attacks.
Recently I have received 28 e-mails from the Scilab Forge site.
The e-mails were sent from bufferblock issue tracker -
http://forge.scilab.org/index.php/p/bufferblock/issues/1483/ .
There are other trackers with spam activity.

Please consider to check security status of Scilab Forge.
It seems to be vulnerable for illegal new user registrations and maybe
something similar.

[Scilab-users] ATOMS does not work on macOS Mojave 10.14.6 - is it a bug? Входящие x IEEE x

[Nikolay Strelkov]

Dear community!

I have strange behavior of ATOMS in Scilab 6.0.2 (downloaded from official
link -
http://www.utc.fr/~mottelet/scilab/download/6.0.2/scilab-6.0.2-x86_64.dmg )
on macOS Mojave 10.14.6.
The ATOMS does not work on Scilab which normally launched from Applications
menu of from launcher (in normal traditional GUI way).

I got the following screenshot if I simply open Application -> "Module
Manager - ATOMS" ends with dialog window with message "No ATOMS module is
available. Please, check your Internet connection or make sure that your OS
is compatible with ATOMS.". See attached screenshot -
https://bugzilla.scilab.org/attachment.cgi?id=4987 .

Installation of single package also seems to be failed:

--> atomsInstall('animaGIF')
Scanning repository http://atoms.scilab.org/6.0 ... Done

regexp: Unknown error.

On next Scilab start the ATOMS module is not installed.
When I launch Scilab from Terminal with

/Applications/scilab-6.0.2.app/Contents/MacOS/bin/scilab-bin

and try to install ATOMS from Scilab Console - I get the following
error output in the terminal:

dyld: Library not loaded:

I have already reported a bug -
https://bugzilla.scilab.org/show_bug.cgi?id=16159 .

Is it just me?
Does anyone have the same problem on macOS Mojave or High Sierra?

Re: [Scilab-users] A collection of Scilab GUI tutorials

[Nikolay Strelkov]

Dear Foad!

At first I should say that your idea is very good.

Then I can share a link to GUI programming thread -
http://mailinglists.scilab.org/Scilab-users-GUI-programming-td4037452.html#a4037453
Please read it for links and maybe tutorials for your collection.

About documentation I can recommend to use Markdown. It may be trasformed
to real book in some time. Currenly Markdown books are written with
bookdown.org RMarkdown dialect. It can produce even TeX books for
publishing (see Bookdown book example <https://bookdown.org/yihui/bookdown/>
).

As an author of very comprehensive GUI for Mathieu Functions Toolbox
<http://forge.scilab.org/index.php/p/mathieu/source/tree/master/demos/mathieu_gui.sci>
I can say that Scilab GUI programming is really still poor documented.

Wish you good luck!

Re: [Scilab-users] Data from XCos plots?

[Nikolay Strelkov]

Dear Pndsc!

It is possible. If you have figure with axis from Xcos model then you can
get its data:

a = gca();
x = a.children.data(:,1);
y = a.children.data(:,2);

and then manipulate them as you need.

Re: [Scilab-users] Unable to update ATOMS packages - Scilab 6.0.1

[Nikolay Strelkov]

Dear all!

It is known bug https://bugs.launchpad.net/bugs/1765503 .

The solution is to use binary version of Scilab 6 as described in this
AskUbuntu answer ( https://askubuntu.com/a/1029164/66509 ).

Official reaction from Scilab developers and/or Debian/Ubuntu maintainers
is highly needed and will be appreciated.
Otherwise Scilab 6 from deb-packages is useless waste of disk resources.
So please take all needed measures on distro-level.

Re: [Scilab-users] arduino toolbox: now available for Scilab 6.0

[Nikolay Strelkov]

Dear Samuel!

Thank you for good news!

It would be very great if Linux version will be available for both Scilab
5.5.2 (as in Ubuntu 16.04 LTS) and Scilab 6.0 (as in Ubuntu 18.04 LTS)
through ATOMS.

I'm ready to test it with Arduino boards - I have Atmega328 based (Uno, Pro
Mini, Nano) and Atmega2560-based (Mega).

Re: [Scilab-users] Installing Scilab under Linux (Mint / aka Ubuntu)

[Nikolay Strelkov]

Dear Claus!

As a temporarily fix you can read this solution on AskUbuntu -
https://askubuntu.com/a/1029164/66509 . I have tested it. Unpacking to home
folder works as expected (and as before).

Dear Scilab developers!

As long-time Scilab user I can't completely understand how this may happen.
Please take a look to the mentioned bugs in the linked answer above and
make real actions to fix these problems. Scilab is completely broken in
Ubuntu 18.04 LTS (so without real actions it will be broken until 2023) and
does not work on development version 18.10 too. Also it does not work on
Debian 10. Please contact Debian and/or Ubuntu maintainers directly.

Scilab is very often used in educational purposes. For example we use it on
Ubuntu 16.04 LTS in our university to teach students.
It will be very bad if we lose such a convenient and useful software-tool.

Re: [Scilab-users] Scilab-6.0.0 stopped working

[Nikolay Strelkov]

Dear Paul!

Seems to be incompatibility between upstream (Scilab.org) and GNU/Linux
distributions.

You can install scilab 6.0.0-1 packages from 18.04 LTS to your 17.10
as described
on AskUbuntu <https://askubuntu.com/a/1003065/66509>.

Re: [Scilab-users] GUI programming

[Nikolay Strelkov]

Dear Claus!

It seems that Scilab GUI programming is not fully described nowadays.

When I programmed my Mathieu Functions Toolbox version 4 with GUI
<http://atoms.scilab.org/toolboxes/Mathieu/> I gathered information from
whole internet.
You can learn GUI programming by analyzing and breaking its main GUI file
<http://forge.scilab.org/index.php/p/mathieu/source/tree/master/demos/mathieu_gui.sci>
(see it's page on Forge
<http://forge.scilab.org/index.php/p/mathieu/page/Demos-0/> ; demo is
available from Scilab: *? -> Scilab Demonstrations -> Mathieu functions ->
GUI for Mathieu Function Toolbox* ) :)

I have bookmarked some pages:

   - http://atoms.scilab.org/categories/GUI - you can download and read
   source code of available ATOMS
   - https://wiki.scilab.org/howto/guicontrol
   - http://cgit.scilab.org/scilab/tree/scilab/modules/gui/demos/
   uicontrol.dem.sce - uicontrols demo 1 (available from Scilab: *? ->
   Scilab Demonstrations -> GUI -> Uicontrols 1* ; locally as
   /usr/share/scilab/modules/gui/demos/uicontrol.dem.sce)
   - http://cgit.scilab.org/scilab/tree/scilab/modules/gui/demos/
   cb_uicontrol_plot3d.dem.sci - uicontrols demo 2 (available from Scilab: *?
   -> Scilab Demonstrations -> GUI -> Uicontrols 2* ; locally as
   /usr/share/scilab/modules/gui/demos/cb_uicontrol_plot3d.dem.sci ) - *it's
   recommended starting point, I think*
   - http://cgit.scilab.org/scilab/tree/scilab/modules/signal_

   - TrityTech present course "Creating Innovative GUI using Scilab" you can
   try to contact them for materials


I have never seen comprehensive book
<http://www.scilab.org/en/resources/documentation/books> about programming
GUI in Scilab (in any language).
So If I remember correctly I read some books about MATLAB's GUI (uicontrol)
function and extrapolated this material to Scilab.

Re: [Scilab-users] SIVP problem via ATOMS with Linux Mint 18.1 - HELP

[Nikolay Strelkov]

Dear Dave!

I got libtiff.so.4 from Ubuntu Saucy (see this AskUbuntu answer -
https://askubuntu.com/a/457034/66509 ).

Then I installed SIVP with
atomsUpdate(); atomsInstall("SIVP");
from Scilab 5.5.2 x64 on Ubuntu Xenial Xerus 16.04 LTS (as your LinuxMint
is based on it).

As was already mentioned on SIVP ATOMS page - symbolics links are broken
inside SIVP archive (
https://atoms.scilab.org/toolboxes/SIVP/0.5.3.2#comment2775 ) .

So with current SIVP version user should do the following from terminal:

cd /home/$USER/.Scilab/scilab-5.5.2/atoms/SIVP/
0.5.3.2/thirdparty/opencv/linux/x64

rm libavcodec.so
ln -s libavcodec.so.52 libavcodec.so

rm libavformat.so
ln -s libavformat.so.52 libavformat.so

rm libavutil.so
ln -s libavutil.so.49 libavutil.so

rm libcvaux.so
ln -s libcvaux.so.4 libcvaux.so

rm libcv.so
ln -s libcv.so.4 libcv.so

rm libcxcore.so
ln -s libcxcore.so.4 libcxcore.so

rm libdc1394.so
ln -s libdc1394.so.22 libdc1394.so

rm libhighgui.so
ln -s libhighgui.so.4 libhighgui.so

rm libml.so
ln -s libml.so.4 libml.so

rm libswscale.so
ln -s libswscale.so.0 libswscale.so


I'm not SIVP and/or OpenCV expert, I did not use it before your e-mail,
but it seems that it works after aforementioned manipulations.
I can run all SIVP Demonstrations.

Hope this helps.

Re: [Scilab-users] Linux: Console not working when starting from start menu

[Nikolay Strelkov]

Dear, Richard!

Yes, it is known issue - see http://bugzilla.scilab.org/
show_bug.cgi?id=14682 .
As temporary solution I created desktop launcher with command inside

env LC_ALL="en_US.UTF-8" xterm -e /home/nikolay/Software/scilab-6.0.0/bin/scilab

So Scilab starts with xterm terminal emulator. You may change xterm to
other terminal with corresponding options.

Hope this helps.

Re: [Scilab-users] Scilab is crashing -- on one machine only

[Nikolay Strelkov]

Dear Tim!

As was discussed In the list (
http://mailinglists.scilab.org/Scilab-users-scilab-gt-Segmentation-fault-td4036624.html
).

This is not Scilab bug, it's bad attempt to fix CVE-2017-1000364 security
bug in Linux kernel.
Debian 7, 8, 9; Ubuntu 14.04 LTS and 16.04 LTS are affected (see
https://bugs.launchpad.net/bugs/1699772).

The *temporary* solution is to reboot with previous kernel versions:
* Debian 7 (wheezy): <= 3.2.78-1
* Debian 8 (jessie): <= 3.16.43-2
* Debian 9 (stretch): <= 4.9.30-2
* Ubuntu 14.04 LTS (trusty): <= 3.13.0-119
* Ubuntu 16.04 LTS (xenial): <= 4.4.0-79

Canonical and Debian will release normal kernel updates soon.

On one machine, Scilab crashes, with a segmentation fault.

On the other, it perks along happily.

The "bad" machine had the normal Ubuntu installation of Scilab (5.5.2),
then I wiped that and installed 6.0.0 -- same thing.  I just
reinstalled the Ubuntu version -- crashes.

scilab-cli works

The "good" machine is the same Ubuntu distro (16.04, 64-bit).

Any clues as to what may be happening?

Re: [Scilab-users] scilab -> Segmentation fault

[Nikolay Strelkov]

After some googling I can summarize the following:

This is not Scilab bug, it's bad attempt to fix CVE-2017-1000364 security
bug in Linux kernel.
Debian 7, 8, 9; Ubuntu 14.04 LTS and 16.04 LTS are affected (see

* Ubuntu 14.04 LTS (trusty): <= 3.13.0-119
* Ubuntu 16.04 LTS (xenial): <= 4.4.0-79

Phillipe, please update your Google+ post
<https://plus.google.com/u/0/+philipperoux/posts/Y1mHTV5KJVf?cfem=1> with
aforementioned kernel versions.

All corresponding bugs in Scilab should be closed as INVALID with reason
"not Scilab bug", I think.

Re: [Scilab-users] Use of optimized ATLAS binary with Scilab (on linux)

[Nikolay Strelkov]

Dear Antoine!

On Ubuntu and Debian you can install Scilab from official repositories and
then switch libblas or liblapack to ATLAS with
update-alternatives (see
https://wiki.debian.org/DebianScience/LinearAlgebraLibraries).
Hope this helps.

Re: [Scilab-users] Get some error

[Nikolay Strelkov]

Dear gnu!

What compiler do you use?

It is known that MinGW GCC works normally. You can install MinGW compiler
from Scilab ATOMS <http://atoms.scilab.org/toolboxes/mingw> (see its
Description).

[Scilab-users] Arduino ATOM on Scilab 5.5.2 under Ubuntu 16.04 LTS

[Nikolay Strelkov]

Dear Scilab users!

Recently I have installed Ubuntu 16.04 LTS, it has Scilab 5.5.2 in
repositories <http://packages.ubuntu.com/xenial/scilab>.

I planned to use it with Arduino Uno board, so I tried to install arduino
toolbox (ATOMS) with
-->atomsInstall('arduino')
atomsInstallList: The package arduino is not available.
 !--error 1

at line  51 of function atomsError called by :
at line  76 of function atomsInstallList called by :
at line 233 of function atomsInstall called by :
atomsInstall('arduino')

so I can't install it.

I can't understand why this toolbox is not available
<https://atoms.scilab.org/?order===arduino=on=_supported_version=5.5>.

It has huge free-software popularization and educational potential. Isn't
it?

Someone opened ticket on Forge
<http://forge.scilab.org/index.php/p/arduino/issues/1556/> to indicate this
problem. But with no results.
It seems that Scilab-forge is half-dead.
I remember the last discussion
<http://mailinglists.scilab.org/Scilab-users-Scilab-Arduino-tt4034546.html#a4034553>
about Arduino and Scilab 5.5.2, it solves the problem, but it is not
newbie-friendly to download, extract and run ATOM-archive manually.

Please compile this toolbox for Scilab 5.5.2 and make it available as ATOM
on all platforms.
Moreover it is not available for Scilab 6 as explained in the new ticket
<http://forge.scilab.org/index.php/p/arduino/issues/1684/> and on ATOMS site
<https://atoms.scilab.org/?order===arduino=on=_supported_version=6.0>
.

Re: [Scilab-users] Define numerator and denominator of transfer function as variables in Xcos (DLR block)

[Nikolay Strelkov]

Thank you, Oleksiy!

I added initial state vectors to the context:
IS1 = zeros(1,length(h1));
IS2 = zeros(1,length(h2));

Now It works as expected.

Re: [Scilab-users] Setting up C-compiler

[Nikolay Strelkov]

Dear Phililip!

I do not know about MS compiler.
I use GCC from mingw on my Windows 8.1 laptop.

I installed version 0.9.3 from ATOMS
<http://atoms.scilab.org/toolboxes/mingw/0.9.3>:
1. installed gcc x64 from -
http://atoms.scilab.org/toolboxes/mingw/0.9.3/files/gcc-4.6.3-64.exe
2. logged out
3. installed mingw toolbox in Scilab with
atomsInstall('mingw');
4. restarted Scilab
5. tested mingw toolbox with
atomsTest('mingw');

Hope this helps.

[Scilab-users] Define numerator and denominator of transfer function as variables in Xcos (DLR block)

[Nikolay Strelkov]

Dear all!

I'm playing with simple digital filtering in Xcos 5.5.2.
I have two filters - low-pass and high-pass, connected in series.

Xcos does not have convolution block.
So I write FIR transfer function
<https://ccrma.stanford.edu/%7Ejos/fp/FIR_Transfer_Function.html> manually
from impulse response function.
I get impulse response functions from wfir function.

Let's assume that we have two simple filters with impulse responses:
h1 = [0.37419570.3741957]; // it's low-pass filter from h1 =
wfir("lp",2,[.2 0],"re",[0 0])
and
h2 = [- 0.18709790.8  - 0.1870979]; // it's high-pass filter h2 =
wfir("hp",3,[.1 0],"re",[0 0])

I convert them to DLR <https://help.scilab.org/docs/5.5.2/en_US/DLR.html>
SISOs and get:
H1(z) = 0.3741957*z^-1 + 0.3741957*z^-2 = ( 0.3741957*z + 0.3741957 ) /
(z^2);
H2(z) = -0.1870979*z^-1 + 0.8*z^-2  - 0.1870979*z^-3 = ( -0.1870979*z^2 +
0.8*z  - 0.1870979*z ) / (z^3);
and place their numerator and denominator to the corresponding DLR blocks.
Model is in attachment. It's an illustration, not real world example.

I have a question. How I can automate the aforementioned process
programmatically?
I tried to create numerator and denominator with poly function and as
strings, but Xcos does not support these types in DLR settings.

Re: [Scilab-users] compiling scilab

[Nikolay Strelkov]

Dear Martin!

First of all can't understand why you are trying to compile Scilab.
You can get binary version <http://www.scilab.org/download/latest>, extract
and use it.

At second you can get Scilab from AUR
<https://aur.archlinux.org/packages/?O=0=scilab>. If you still willing to
compile Scilab from sources you should install its build dependencies.
I think you can start building Scilab 6.0.0 (commit
22bd3a5c93489bce74fbaf25d19fe55aefca853c
<http://gitweb.scilab.org/?p=scilab.git;a=commit;h=22bd3a5c93489bce74fbaf25d19fe55aefca853c>
).
After successful build of 6.0.0 you can try newer revisions.

I'm on Ubuntu 12.04.5 LTS. Here we use "apt-get build-dep scilab",
"checkinstall" and so on
<http://mailinglists.scilab.org/Compilation-Errors-tc4035596.html#a4035619>.
So I can't offer more.

[Scilab-users] MinGw toolbox 0.10.0 is not compatible with Scilab 6.0

[Nikolay Strelkov]

Dear Scilab users and developers!

I have installed Scilab 6.0 x86 and x86_64 on my Windows 8.1 x86_64 laptop.

Also I have downloaded and installed gcc-6.2.0 for x86
<http://atoms.scilab.org/toolboxes/mingw/0.10.0/files/gcc-6.2.0-32.exe> and
x86_64
<http://atoms.scilab.org/toolboxes/mingw/0.10.0/files/gcc-6.2.0-64.exe> as
prerequisites of MingGw toolbox
<https://atoms.scilab.org/toolboxes/mingw/0.10.0>.
Then I installed MinGw toolbox in Scilabs with atomsInstall('mingw'). This
process was successful.
Then I restarted Scilab and tried to test MinGw toolbox with
atomsTest('mingw').

The results are not good - on both x86 and x86_64 - 13 tests of 15 are
failed. Only *G_make* and *dllinfo* are passed.
I do not attach logs - the error is always the same "failed: Slave Scilab
exited with error code 1 ".

If I launch these unit-tests manually (with cd SCIHOME\atoms\x64\mingw\0.10.
0\tests\unit_tests\ and corresponding exec *.tst )
I got messages such as

WARNING: C:\Users\nikolay\AppData\Roaming\Scilab\SCILAB~2.0\

Also I tried to launch Xcos model with Modelica blocks with

then with Simulation->Start got error in console

reports 10 passed tests (failed are: *addinter, ilib_build, ilib_build_2,
ilib_build_cpp, links*).
But Xcos models with Modelica blocks can be simulated except 2 crashes (*Ball

Scilab 5.5.2 (x86 and x86_64) works normally on the same machine with
mingw-0.9.3 (and gcc-4.6.3).



Where is an error - in Scilab or in MinGw toolbox?
Should I report bug?

Re: [Scilab-users] Scilab - Arduino

[Nikolay Strelkov]

Dear Paul!

I'm on Ubuntu 12.04.5 LTS amd64 with binary Scilab 5.5.2 amd64.

I downloaded Arduino toolbox from link in this comment (Francisco-Ronay
Lopez-estrada -- July 16, 2015, 07:51:43 PM
<https://atoms.scilab.org/toolboxes/arduino/1.1#comment2474>) - Arduino
linux3.zip
<https://mega.co.nz/#%21T1RynDrI%21icxPWmHxbNhqPnIXpHr2wIxhipXWeNb0hRSDHu00RQQ>
.
I extracted this zip-archive to my SCIHOME directory (
/home/nikolay/.Scilab/scilab-5.5.2), then launched builder.sce and then
added loader.sce to autoload by creating
/home/nikolay/.Scilab/scilab-5.5.2/.scilab with the following line:
exec('/home/nikolay/.Scilab/scilab-5.5.2/linux3/loader.sce',-1);
Then I restarted Scilab and Arduino toolbox loaded with messages:
Startup execution:
  loading initial environment
Start Arduino
Load macros
Load serial dll
Shared archive loaded.
Link done.
Load palette
Load help
Load demos
Arduino Version: 1.2
-->

In Ubuntu your user should be a member of dialout group - sudo adduser
$USER dialout .
For better Scilab usability I suggest to use light window manager theme,
for example Radiance.
After this you can use Arduino with Xcos.
You can vote for official linux port of Arduino toolbox on forge
<http://forge.scilab.org/index.php/p/arduino/issues/1556/>.

Hope this helps.

Re: [Scilab-users] How to plot frequency spectrum in Xcos for Scilab Version 5.5.2(64 bit)

[Nikolay Strelkov]

Dear Parthageet Samantaray!

You are right about PSPECSCOPE_с
<http://www.scicos.org/ScicosModNum/modnum_web/src/modnum_43b/interf/scicos/help/eng/htm/PSPECSCOPE_c.htm>
in Modnum toolbox. For now it is available only for ScicosLab
<http://www.scicos.org/downloads.html>.
There is a project from Peter Fabo for porting Modnum to modern Scilab (see
here <http://wiki.tntech.eu/index.php?title=Xcos_Modnum> and in the mail
list
<http://mailinglists.scilab.org/Scilab-users-Modnum-amp-Xcos-td4027491.html>
).

I prefer to use Scilab with Xcos, so I suggest the following solution
(tested on 5.5.2 x64):
1. Create Xcos model with variables - see *sine.xcos*
2. Create Scilab script file for launching Xcos model and plotting result
as function of time and frequency (with built-in FFT function) - see
*sine_launcher.sce*
3. Launch *sine_launcher.sce* and it will simulate Xcos model and plot FFT
for it

Hope this helps.

Re: [Scilab-users] Strange behaviour of char(?) function in scilab-6.0.0-alpha-1

 Release notes announce changes with cells: cell.entries and cell.dims have
 been removed.
 But cellstr.sci has not been updated (and may be other macros?):

 edit cellstr

[Scilab-users] Strange behaviour of char(?) function in scilab-6.0.0-alpha-1

[Nikolay Strelkov]

Dear Scilab community and developers!

In my project I have the following code (simplified for clarity):

vals = [cellstr('aaa'),cellstr('bbb'),cellstr('ccc'),cellstr('ddd')];


for n = 1:size(vals,*)
val = char(vals(n));

printf(\n%s,val);

if val == aaa then
disp('got aaa');
end
end;


It works as expected in Scilab 5.2.2, 5.3.0, 5.3.2, 5.3.3, 5.4.0, 5.4.1,
5.5.0, 5.5.1, 5.5.2 and in ScicosLab 4.4.1.

But it does not work in Scilab 6.0.0-alpha1.
Here I get error:
exec('/tmp/cell_problem.sci', -1)
char: Wrong type for input argument: Cell expected.
at line95 of function char (
/home/norbert/Downloads/scilab-6.0.0-alpha-1/share/scilab/modules/compatibility_functions/macros/char.sci
line 104 )
at line 5 of executed file /tmp/cell_problem.sci


So my questions are:
1. Did you change something in char function in Scilab 6?
2. How should I change my code to make it working in Scilab 5.x and 6 with
the same functionality?
3. Do I need to report bug?

Re: [Scilab-users] Previous Scilab version.

[Nikolay Strelkov]

Dear, Mario!

You can download Scilab 5.2.1 for example from here (
http://uni-smr.ac.ru/archive/win/science/math/scilab/5x/win/ ).

But I think you do not need exact version, because of stable Scilab syntax.
Moreover modern versions of Scilab are more user-friendly.

  To Scilab team

 I've bought the book CURVES AND
 SURFACES How to draw different shapes through SCILAB edited by Pitagora in
 Bologna, Italy.

 Now I learn that I must download an old version of SCILAB, namely 5.2.1.

 I was going to mail the Previous Scilab Version form.

 However I got stuck with the question: What kind of archive do you need ?
 Binary, Sources, Prerequirements?

 I ask kindly help from you as far as *what is the right answer* to the
 above request, when I want to download the SCILAB program as is normally
 done from the Scilab.org internet site.

 The OS here is 32-bit Windows XP.

 I intend to use the Scilab program merely for personal educational
 purpose. No commercial usage is foreseen.

 Thanks for the help.

 So I have no problems with A4-4000 APU.
 What exact laptop model do have?
 I understood about AMD A10. But may be there is a discrete (hybrid) card
 too?

 For what it's worth, in Lubuntu the full fglrx packages causes immediate
 crashes, while uninstalling all fgrlx-related stuff except for fgrlx-core
 makes it last a while before it dies.

 Also, this computer was a rush job to replace my rather old previous
 machine which died Monday morning, and all I did to install the OS was to
 use the old hard drive.  As a consequence, the new machine is running in
 32-bit mode, not 64.  I'm not sure how mature the 64-bit stuff is, or how
 neglected the 32-bit stuff may be at this point.

Re: [Scilab-users] New computer, graphics(?) crashes

[Nikolay Strelkov]

Could you try to reinstall package containing missed
/usr/lib/i386-linux-gnu/egl/egl_gallium.so with

sudo apt-get install --reinstall libegl1-mesa-drivers
?

Did you try to install scilab 5.3.3 from ubuntu repositories (sudo apt-get
install scilab)? Does it work?
Manual unpacking 5.5.1 to /usr/local may cause missed system dependencies.
On my ubuntu I have many scilab versions - 5.3.3 from repository and newer
versions (unpacked to ~/Software with custom  launchers on desktop).

 Dear Peter Fabo and all!

 It is great, that Modnum being ported to modern Scilab and Xcos!

 I'm very interested in PSPECSCOPE_с
 http://www.scicos.org/ScicosModNum/modnum_web/src/modnum_43b/interf/scicos/help/eng/htm/PSPECSCOPE_c.htm
 (for FFT) and CONVOLGEN_f
 http://www.scicos.org/ScicosModNum/modnum_web/src/modnum_43b/interf/scicos/help/eng/htm/CONVOLGEN_f.htm
 (for FIR filtering) blocks.
 For FFT there is an project in Scilab Forge (bufferblock
 http://forge.scilab.org/index.php/p/bufferblock/), but it does not
 compile in modern versions of Xcos and Scilab (see issues
 http://forge.scilab.org/index.php/p/bufferblock/issues/). But I saw a
 paper where it was used with Scilab =5.3.

 I think it would be great if you place your work in Scilab Forge
 http://forge.scilab.org.
 I'm ready to test your toolbox.

 Hi all,
 Any news on the availability of MODNUM converted to XCOS?
 I am interested in the PLL palette.
 Thx much,
 Gilles.

Re: [Scilab-users] Bessel functions

[Nikolay Strelkov]

Dear Claus!

For me it seems that using standard functions is always better, than
writing them from scratch.

So I recommend to use built-in Scilab functions besseli, besselj, besselk,
bessely, besselh http://help.scilab.org/docs/5.5.1/en_US/bessel.html.

  Hi

 I've made a small script to play around with Bessel functions of the first
 kind... but this is very basic and I'm wondering if there's a smarter way.

 Below is the script I made (the function + a small test which plots the
 result).

 Best regards,
 Claus

 // bessel_test.sce
 function z=Jn(n, x)
 // The following power series approximates the nth Bessel
 // function of the first kind for each input x
 // In acoustics x = 2ka, defines the iput frequency k = omega / c and size
 // of the piston radiator
 powerseries = 0;
 for m=0:19 // actually it should be infinity, but 10 approximates OK ...
 powerseries_m = ((-1)^m / (factorial(m) * factorial(m + n))) * 
 (x/2)^(2*m);
 powerseries = powerseries + powerseries_m; // sum the powerseries
 end
 z = ((x/2)^n) .* powerseries;endfunction
 x_array = 0:0.1:9.9; // define 100 points on the x-axis
  // with 2ka (x) from 0 to 10, and with m = 0-19,
  // this approximation is reasonably good for 2ka  10
 z_0_array = Jn(0,x_array); // Calculate J0
 z_1_array = Jn(1,x_array); // Calculate J1
 scf();a = 
 gca();plot(x_array,z_0_array,'-b');plot(x_array,z_1_array,'-r');xtitle(Bessel
  functions,x (2ka),output (z));legend(J0,J1);

Re: [Scilab-users] Bessel functions

[Nikolay Strelkov]

In modern Scilab these functions are called from Fortran library.
Here is its source
http://gitweb.scilab.org/?p=scilab.git;a=blob;f=scilab/modules/special_functions/src/fortran/dbesjg.f
.

  Hi Nikolay, et al.

 You're right, I should have checked Scilab help for Bessel functions
 before trying to do my own.

 I executed besselj(0,x_array) as well as besselj(1,x_array) ... it seems
 that this function works exactly like what I made myself. And the output is
 indistinguishable (for the range I'm interested in).

 Trying to find the Scilab code for besselj, I see that it's an uneditable
 and hard coded. Is there anywhere I can study in detail how besselj was
 coded?

 Best regards,
 Claus

Re: [Scilab-users] subplot problem

[Nikolay Strelkov]

Hello, rathodprashnt !

You need to move plot(x,y) to the end of for loop.

t=0:0.01:10;
x=cos(2*%pi*t); theta=0

for k=1:4
y=cos(2*%pi*k*t);
if k==1 then subplot(221)
elseif k==2 then subplot(222)
elseif k==3 then subplot(223)
elseif k==4 then subplot(224)
end
*plot(x,y);*
end

I recommend you to read/watch some tutorials on Scilab (
http://www.openeering.com/scilab_tutorials or
http://www.scilab.in/spoken-tutorial ).

 Hy  i am new to scilab and i am trying to run new with subplot command
 using
 (221) to (224) format but some how out of 4 subplot only last one is
 visible.

 here is my script
 _

 t=0:0.01:10;
 x=cos(2*%pi*t); theta=0

 for k=1:4
 y=cos(2*%pi*k*t);
 if k==1 then subplot(221)
 elseif k==2 then subplot(222)
 elseif k==3 then subplot(223)
 elseif k==4 then subplot(224)
 end
 end
 plot(x,y);

Re: [Scilab-users] [scicos] Fwd: Question about PSPECSCOPE_с in Modnum toolbox

[Nikolay Strelkov]

Thank you for reply, Ramine!

I tried to change parameters as you recommend after your suggestion and
before it.
It does not solve the problem.
FFT figure window is empty, but I expect peak at 1 Hz.

 Hi, I am not familiar with this block but the parameters don't seem to be
 correct. The period of sample clock in the model is 1e-3 but the sampling
 period block parameter of this block is not 1e-3. I also note that the size
 of input buffer is 2048 but the simulation stops at 2, i.e., 2000 points. I
 assume no FFT is computed until at least 2048 points are placed in the
 buffer.

 Subject: Question about PSPECSCOPE_с in Modnum toolbox
 To: alan.la...@cermics.enpc.fr


 Dear Alan!

 Thank you for your great Modnum toolbox. I use it from 2009 year for
 modelling of some control system elements.

 Today I use Modnum 4.3b with ScicosLab 4.4.1.
 I want to create a simple demo with PSPECSCOPE_с block for calculating and
 plotting FFT spectrum of a simple sine wave.

 As a starting point I created small file in Scilab 5.5.1 which plots and
 calculates FFT spectrum. It is in attachment, and it works as I expect.

 I created Scicos model file, but I can't understand how to set correct
 options for PSPECSCOPE_с block for getting expected FFT. The model file is
 in attachment.

 Could you please help me to set up PSPECSCOPE_с block?
