I guess you've red the help page of "axes properties" to find the solution, 
where is it written: "Changing by hand the Locations or/and Labels of an axis 
automatically sets its .auto_ticks status to "off"". There is nothing about 
"Step by", that exists on the "Edit Axes Ticks" box!

Re: [Scilab-users] Graphic problem with ubuntu 22.04

I’ve just upgraded ubuntu to 22.04 LTS version (Linux 5.15.0-75-generic)

are ok but I’ve no graphic output for both scilab 6.1.1 and 2023.1.0.
The graphic window opens but nothing is displayed and docking buttons
aren’t available.

I suppose there is a problem with the graphic driver, does anyone have
some clue about this ?

Hello,

I wrote the vector "a" on the file "test.sce" and did

--> exec test.sce;
--> size(a)
ans  =

   1.   371.


Tested on Scilab 6.1.1. So it seems to work fine. I also tested a row
vector of 1 "1" and it works also! (I have many sce files like that,
because I use to add "a=[" at the beginning of ascii-matrix data files,
and "];" at the end. Maybe it's not the most efficient way to read and
store data, but it's the simplest for me :-)

[Scilab-users] plot and subplot bug for low values?

The following code gives strange results (Scilab version

subplot(212),plot(1e-8*rand(1,5))

the y-axis and the y_ticks are not only limited to the subplot! The same
appends with full plot (without subplot) and there exist y_ticks above
the graphic window.

Is it a bug with low value?

The installation of java is complete, with configuration issues
remaining.

You must use update-alternatives for java and javac.

  $  sudo update-alternatives --config java
  $  sudo update-alternatives --config javac

What you have to enter is the previous number (2 in the table above),
not the back number.
Maybe even 2 in javac.

And put the following in your .bash_profile.

JAVA_HOME=$(readlink -f /usr/bin/javac | sed "s:/bin/javac::")
export JAVA_HOME

Then, execute as follows

$ source ~/.bash_profile

After this , by

$ echo $JAVA_HOME



###
wolfgang@Fuji:~$ echo $JAVA_HOME
/usr/lib/jvm/java-11-openjdk-amd64

in my .bash_profile is:

JAVA_HOME=$(readlink -f /usr/bin/javac | sed "s:/bin/javac::")
export JAVA_HOME

#


Confirm that it returns following

/usr/lib64/jvm/java-1.8.0-openjdk-1.8.0

This completes the JAVA setup.

Re: [Scilab-users] output buffer

[Jean-Yves Baudais]

Hello,


Le 17/06/2022 à 23:45, Stephane Mottelet a écrit :
The buffer size is not set by Scilab and hence is always the default for 
a given platform (it can be different for macOS, Linux, Windows). I 
suppose you need to increase or decrease it for a given application?



It is just for convenience. Here a better explanation. During 
simulation, I write some variables on file (used latter for statistical 
analysis) and I use to prepare and test the post-processing using the 
partial output data. Scilab does not write the data one by one, but by 
block of size 4096. The following code shows this behaviour.



--> function stupidWrite(fd,n,a)
--> for i=1:n mfprintf(fd,"%d",a); end
--> endfunction
--> fd=mopen("test.am","a");
--> stupidWrite(fd,4096,1);
--> unix_g("cat test.am | wc ");
 ans  =
  "  0   0   0"
--> stupidWrite(fd,1,2);
--> unix_g("cat test.am | wc ");
 ans  =
  "  0   14096"
--> mclose(fd)
--> unix_g("cat test.am |wc ")
 ans  =
  "  0   14097"


With the C language, the size of the output buffer is managed using 
setvbuf. It seems that there is no interface for C-coded version of 
setvbuf (contrary to many input/output C function).


So my question is: "is it possible to manage the size of the output 
buffer in Scilab?"


The solution I found is to mopen and mclose the file each time I want to 
write something. Is there another solution?

[Scilab-users] output buffer

[Jean-Yves Baudais]

Hello,

How can we manage the output buffer when we write to a file? It seems 
that this buffer size is 4096.


Thanks,

[Scilab-users] unloader.sce

[Jean-Yves Baudais]

Bonjour,

Is there a simple way to clear all the used functions of a given library, 
because unloader.sce only remove the library from the "who" list, but not the 
functions that have already been used and that stay in memory, unfortunatly!

Thanks,

Re: [Scilab-users] How to list the content of the recursion stack?

[Jean-Yves Baudais]

Hi,

> from
> --> currentMaxDepth = recursionlimit()
> currentMaxDepth =
> 1000.

Thanks Samuel, I didn't know this function. So I face a problem (a bug?): 
Scilab cratches with segfault but without reaching the recursionlimit. Here the 
used three functions

function out=test_l(in)
  if in==0 then
out=in;
return
  end
  out=in+test_l(in-1);
endfunction

function out=test_ll(in,acc)
  if in<=1
out=acc;
return
  end
  out=test_ll(in-1,acc+in);
endfunction

function l_test(in)
  i=1;
  while 1
mprintf("\n%d: ",i)
sleep(.5,"s");
select in
 case 1
  out=test_l(i);
 case 2
  out=test_ll(i,1);
end
mprintf("%d\n",out)
i=i+1;
  end
endfunction

There is no problem with

> recursionlimit(20)
> l_test(1)

The program stops as expected with the message "Limite de récursion atteinte 
(20)" when i=19 and

> recursionlimit(20)
> l_test(2)

stops when i=20 (I was wrong when I talked about tail call in my previous 
email!). But, with

> recursionlimit(1000)
> l_test(1)

Scilab cratches at i=41 with segfault and with

> recursionlimit(1000)
> l_test(2)

Scilab cratches at i=140. Is this cratch a know bug? (It's quite far from the 
recursion limit!)

(Subsidiary question: while l_test(2) stop 1 iteration after l_test(1) with low 
recursion limit, l_test(2) allows around 100 iterations more than l_test(1) 
before cratch with recursionlimit(1000)! Where does it comes from?)

Re: [Scilab-users] How to list the content of the recursion stack?

[Jean-Yves Baudais]

Hi,

> [...] When we get a Recursion limit reached (1000) message [...]


  I'm not a wizard on programming, not at all, and recursion call it's all the 
time complex for me to use. Anyway, I tested two different recursions and I'm 
really far from the "Recursion limit"! Here the examples:

function out=test_l(in)
  if in==0 then
out=in;
return
  end
  out=in+test_l(in-1);
endfunction
//calling sequence
// test_l(n); // max n=41

function out=test_ll(in,acc)
  if in<=1
out=acc;
return
  end
  out=test_ll(in-1,acc+in);
endfunction
//calling sequence
//test_ll(n,1); // max n=140


test_ll improves a bit test_l because it uses tail call, but the max without 
seg.fault is far from 1000. Where does this limit of 1000 come from?

Re: [Scilab-users] Scilab stops calculus

[Jean-Yves Baudais]

Hi,

  Bad news for me, but good ones for Scilab. I checked the following code

i=0;
a=getdate();
while 1 then
  i=i+1;
  b=getdate()-a;
  mprintf("%d: %d/%d %d:%d:%d,%d\n",i,b([6,2,7:10]));
  sleep(1,"s");
end

on two computers, desktop Ubuntu 16.04 Gnome X11 and laptop Ubuntu 18.04 
Gnome X11, with and without GUI during more than 38 hours, and in the 
four cases Scilab didn't froze. So, no problem for Scilab. (But the 
mystery remains, only for me.)

It was. I tested the following

and there is no problem up to i=2e8 with -nwni option, and up to i=5e7 with gui

[Scilab-users] Scilab stops calculus

[Jean-Yves Baudais]

Hello,

  Two times Scilab was stuck after 20 hours of simulation (I used to do 
simulations that need more than one week with Scilab 5). It was big simulation 
with many levels of iterations (to evaluate probabilities), with intermediate 
results written in files (different files with save command and timestamp), and 
with the iteration numbers written in the Scilab window (so many output lines). 
All worked fine still Scilab locks with:
- no CPU activity (Scilab really stops all calculus, but not exits),
- low memory use as expected (no mem leakage),
- the Scilab window blocked, showing the intermediate iteration numbers (Scilab 
is blocked within an iteration, there is no input-output issues in this part of 
the code), but nothing can be done (CTRL-C, CTRL-D or any control command).
I must kill the Scilab process within a Shell terminal. I also executed the 
"faulty" iteration alone (with 1e4 sub-iterations in more or less 2 hours), but 
there is no problem. I obtained the result. So I can get around the problem, 
but not solved it.

Is there some known limitations? limited prompt lines for example...

Thanks

Oh, maybe I was not clear. The memory issue is not here. There is not 
problem to compute z. The loop is used to show the problem: it seems 
that interp doesn't free the used memory after each call. So after 
hundreds of call Scilab is killed!


for i=1:1000
  mprintf("%d\n",i);

I don't if there is a dedicated function, but 

colour=["red","blue","chocolate1",...]; // help color_list
for j=1:20
  plot(TestPH(j,:))
  gcf().children.children.children(1).foreground=color(colour(j));

I saw that some messages are written on XTERM and not on Scilab window.

Well, I did new test with a simple function in home+"/macros"

function out=testadd(a,b)
  // To test process for lib
  //
  // Syntax
  //  out=testlib(a,b)
  // Parameters
  //  a: scalar
  //  b: scalar
  // Description
  //  Add to scalar
  // Author
  //  Me
  // Bibliography
  //  Nothing
  out=a+b;
endfunction

and I generate the lib "testlib". Contrary to what I wrote, that works fine. I 
did mistake when I used clear. It must be
--> clear testlib testadd
and not
--> clear testlib, testadd
(testadd should also be cleared if it has been called, because 
load("macros/lib") is not enough to replace the function already loaded in 
Scilab memory, I guess)

So, there is no problem with the updated library though the load is fisrtly 
done in .scilab. I don't need to restart Scilab to use the updated library 
"testlib".

The problem still remains for the help:

--> help_from_sci("macros","help/gl_GL")
help_from_sci: Reading from directory macros
help_from_sci: Processing of file: macros/testadd to help/gl_GL/testadd
help_from_sci: processed 1 files.
ans  =
""

Of course I created the help/gl_GL directory before, otherwise there is an 
error, and testadd.xml is created (gl is for globish, english is out of my 
reach)

--> xmltojar("help/gl_GL","My test lib","gl_GL")

jar/scilab_gl_GL_help.jar is udpated, and there is also a message in the linux 
XTERM with the number of generated files.

--> add_help_chapter("My test lib","jar")
T

--> help

The chapter "My test lib" is in the help window with the function testadd.

--> del_help_chapter("My test lib")
--> help

The chapter is not in the help, as expected.

--> add_help_chapter("My test lib","jar")
T

I change the head comment and rebuilt the help:

--> help_from_sci("macros","help/gl_GL")

"/home/jbaudais/jar/scilab_gl_GL_help.jar", on the filesystem of course, but 
Scilab use its memory (stack, heap?) and not the filesystem. Maybe the 
"scilab_gl_GL_help.jar" is corrupted by xmltojar on the Scilab memory. What do 
you think?


I try 
--> del_help_chapter("My test lib")

before modification, and

--> add_help_chapter("My test lib","jar")

but that change nothing. I must restart scilab and

--> add_help_chapter("My test lib","jar")
--> help

it works fine. 

So, I have no solution to rebuilt the help without Scilab restart, from 
scratch! I think the corresponding Scilab memory is not correctly updated or is 
corrupted somewhere (xmltojar, add_help_chapter?), so we must restart Scilab. 
Do you have the same behaviour?

-- Jean-Yves

PS : I read the discussion about profile and did test. Is there similar tool to 
check memory within Scilab, or do we need to use external tools as valgrind?

No, that appends for all size equal or more than 10x10. There is not problem

Yes I can do that using save and load, but my code is not finish and to debug

Hum... 16.04. I know, I have to update. About Scilab, I also used 6.1 but not 
on my computer. (One day I should "rationalize" my numerical tools.) I wonder 
if the segfault comes from multiple CPU use, but I don't know how to check that.

[Scilab-users] Segfault with inv, det...

[Jean-Yves Baudais]

Hello,

  I'm still working on scilab-5.5.2 (I will update my Ubuntu but I 
would like to wait a bit. It's not a good time for me!).


--> det(zeros(10,10))

produces Segmentation fault. There is no problem with lower matrix size, 
and there is no problem at all if I use "scilab -nwni" and higher matrix 
sizes.


"scilab -debug" gives

Thread 1 "scilab-bin" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x77f9f780 (LWP 14031)]
0x7fffe8c9a343 in dgetrf_parallel () from /usr/lib/libopenblas.so.0

before stopping, but I don't know if it is relevant because there is not 
problem with "scilab -nwni"!


Is there a simple way to solve this segfault, still using scilab-5.5.2?

Many thanks,

[Scilab-users] Update library and help

[Jean-Yves Baudais]

Hello,

  When I modify the file myfunction.sci in my librairie "mylib", the 
update works as expected when I restard Scilab with the following lines 
in my .scilab file


genlib(SCIHOME+"/mylib/macros")
load(SCIHOME+"/mylib/macros/lib")
add_help_chapter("Librairie perso",SCIHOME+"mylib/jar")

I would like to do the update without Scilab exit and restart, so I do

--> del_help_chapter("Librairie perso")
--> clear mylib myfunction
--> genlib(SCIHOME+"/mylib/macros")
--> 
help_from_sci(SCIHOME+"/mylib/macros/myfunction.sci",SCIHOME+"/mylib/help/fr_FR");

--> xmltojar(SCIHOME"/mylib/help/fr_FR","Librairie perso","fr_FR");
--> load(SCIHOME+"/mylib/macros/lib")
--> add_help_chapter("Librairie perso",SCIHOME+"mylib/jar")

Excepted genlib and xmltojar, not all the code lines work all the time 
(some time yes and some time no). I understand nothing because I not 
able to reproduce "deterministically" the success, or not! So I think my 
code is wrong.


What is the good code to update library and help after changing a file?

Thank you for the recall on floating point representation and for the link (the 
French wiki page on IEEE 754 gives also a full and clear example). Of course we 
can convert float64 from finite binary representation to decimal one with more 
than 16 digits, but in that case the binary to float tranform is not a 
"relation binaire univoque" and the finite number representation problem is 
"put under the carpet". As I prefer one-to-one convertion and I hate carpet, I 
use 16 digits at most to write float64.

So now the problem can be how these large numbers are obtained

Hum... What does "exact" mean in numerical calculus? (In symbolic one, it's 
simpler :-)

--> format(25)
--> %pi
3.141592653589793115998

the 6 last digits are wrong (cf. https://oeis.org/A000796) because of float64 
format.

Maybe noise is not the right word. But, the difference is fixed and %pi give 
all the time the same digit in format(25). It's a bit weird (up to my 
ignorance) to have these wrong deterministic digits... Hum, maybe I need to 
read "What Every Computer Scientist Should Know about Floating-Point 
Arithmetic", David Goldberg, ACM Computing Surveys, vol. 23, no  1, mars 1991

You face the limited precision of all numerical calculus. See

It has no sense to use 23 digits with a precision of 2.22E-16, the 7th 
last digits are noise.

All is consistent with the definition of the precision. A toy example:
--> a=2;
--> b=sqrt(2);
--> a-b^2

You expect zero because you do symbolic calculus, not Scilab.


The Wolfram Alpha site yields the correct value 0 in all cases (using 
their own pi).



Because it uses symbolic calculus. So, if you want more precision with 
Scilab you should change the standard used, but maybe some tricks in 
your code can solve the problem... Or maybe you need symbolic calculus tool.

As I already said

I don't know where it comes from, but clearly the source code is ok with

It looks like Scilab 5.2.2 is able to free some memories but not Scilab

The difference between emd_toolbox-1.2-1 and emd_toolbox-1.3 are the "void 
*pvApiCtx" added in cemdc.c, cemdc2.c, cemdc_fix.c, cemdc2_fix.c, emdc.c and 
emdc_fix.c. Could that be the source of the memory problem?

I checked "diff" of sci files in emd_toolbox-1.3 and emd_toolbox-1.2.1 (the one 
working on scilab-5.5.2). The differences I found are about emd_ prefix added 
to function names (and the incomprehensible remove of moc_fliplr). I will check

Re: [Scilab-users] atomsLoad

[Jean-Yves Baudais]

Hi,

I fixed the problems. The modifications are

1) emd.sci file, line 410
"//pause"
becomes
"pause"

2) emd.sci file, line 683
opt_fields = 
{'t','stop','display','maxiterations','fix','maxmodes','interp','fix_h','mask','ndirs','complex_version'};
becomes
opt_fields = 
['t','stop','display','maxiterations','fix','maxmodes','interp','fix_h','mask','ndirs','complex_version'];

3) emd.sci file, line 794
if ~type(INTERP)==10 | 
~or(convstr(INTERP)==convstr({'linear','cubic','spline'}))
becomes
if ~type(INTERP)==10 | 
~or(convstr(INTERP)==convstr(['linear','cubic','spline']))

4) emd_local_peak.sci, line 32
lm = find(diff(a)~=1) + 1;
becomes
lm = find(diff(a)~=1); if lm==[], then lm=1; end

5) boundary_conditions_emd.sci file, the function moc_fliplr should be added at 
the end of the file
function y = moc_fliplr(x)
//  Copyright Aldo I Maalouf
if ndims(x)~=2,
disp('X must be a 2-D matrix!')
end
y = x(:,$:-1:1);
endfunction

The modification 1) is really a minor one. The remove of moc_fliplr() function 
in boundary_conditions_emd.sci file is very strange (this function exists in 
older emd_toolbox version!).

I only tested the emd() function and it gives the same output with toy examples 
as the ones obtained with emd_toolbox of repository 5.4 (tested on 
scilab-5.5.2). However, I didn't test all the paramaters of the function.

It remains one problem: the memory used always increases. If emd() function is 
ran multiple times, my 8G mem is fulfilled by scilab and of course scilab 
crashes. Maybe this comes from the modified sources of emd_toolbox done by 
Stephane Mottelet? (Note that there is no memory issues with emd() function of 
repository 5.4.)

[Scilab-users] file permission and demo_gui()

[Jean-Yves Baudais]

Hello,

  When I installed Scilab, I unziped the file on my home directory. The 
permission for all files is read only, and execute if needed. Then, the 
demo_gui() needs to be executed twice to work.

The first time, in file demo_gui.sci:
- line 54, the permission of 'File' is read only;
- line 55, 'File2' has not been created yet;
- line 58, 'File2' is created with the same permission as 'File';
- line 65, 'xmlWrite' cannot write because of read permission only and 
demo_gui() stops with the error message "Cannot write the file...".

The second time 'File2' exists, then demo_gui() works.

By default, unzip doesn't change the permission, timestamp... So, is it a bug?

and "scilab -nogui" gives (maybe more informative)

Scilab startup function detected that the function proposed to the engine is 
the wrong one. Usually, it comes from a linker problem in your distribution/OS.
Here, Scilab should have 'libscijvm-disable' defined but gets 'libscijvm' 
instead.
If you do not know what it means, please report a bug on 
http://bugzilla.scilab.org/. If you do, you probably know that you should 
change the link order in SCI/modules/Makefile.am

Is there a simple way to solve this JVM problem? (Note that the default 
scilab-6.0 installed in my Unbuntu has a JVM problem also and does not work. 
Maybe I will try to solve it another time.)

Re: [Scilab-users] atomsLoad

Hi,

  Thank you for the explanations. They make me the atom philosophy clearer :-)

Yes, and I understand now it's rather good nothing was installed because the 
atoms "emd_toolbox" is not compatible with Scilab-6.1.

Yes, but I have to learn and I'm more irresponsible to do what I did :-)

So, I think the best way it to use older Scilab version because 
- only too old emd_toolbox is "atomsInstalled" with Scilab-6.1 and not 
"atomsLoadable"
- with http://atoms.scilab.org/5.3 repository, the atomsLoad() function alway 
gives "bad library path"
- I'm not able to start with library source code

Two questions:
- Which Scilab version should I used? (only 5.5.2 or 5.1.1 are available on 
http://www.scilab.org)
- Is the message "bad libray path" given by atomsLoad() mean there is a 
compatiliby issues? If yes, why does atomsInstall() intall without any error 
while atomsLoad() give errors?

Thank for all,

Hi,

> Hard to help without knowing what you exactly did to install the toolbox, 

As I wrote I did
--> atomsRepositoryAdd("http://atoms.scilab.org";)
--> atomsInstall("emd_toolbox")
--> atomsLoad("emd_toolbox")

Nothing else.

Ok. So the error message "lib: [...] is not a valid lib path" does not mean the 
path does not exist but the version 1.2-1 cannot be used. Right?

Hum... I chosen nothing, I let Scilab functions atomsInstall() and atomsLoad() 
do the job...

[Scilab-users] atomsLoad

[Jean-Yves Baudais]

Hi,
  I face problem with atomsLoad. (It's the first time I use atoms!)

1) I installed scilab-6.1.0.bin.linux-x86_64.tar.gz on my $HOME.
2) I added the atoms repository http://atoms.scilab/org because the default one 
is http://atoms.scilab.org/6.1 and it gives nothing!
3) I installed emd_toolbox and the installed files are on 
$HOME/.Scilab/scilab-6.1.0/atoms/ ($HOME/.Scilab/scilab-6.1.0 is the SCIHOME 
variable in Scilab)

So far, all is good. But the next step, atomsLoad("emd_toolbox") does not work. 
The message is

atomsLoad: An error occurred while loading 'stftb-1.2-1':
lib: /home/jbaudais/.Scilab/scilab-6.1.0/atoms/stftb/1.2-1/macros/ is 
not a valid lib path.
at line   346 of function atomsLoad ( 
/home/jbaudais/scilab-6.1.0/share/scilab/modules/atoms/macros/atomsLoad.sci 
line 362 )

Note: emd_toolbox needs stftb but if I try atomsLoad("stftb"), the result is 
the same.

I don't understand because the directory 
/home/jbaudais/.Scilab/scilab-6.1.0/atoms/stftb/1.2-1/macros/ exists and it 
contains the "names" file and all the .bin, .sci files.

Any ideas?

Re: [Scilab-users] String and integer

[Jean-Yves Baudais]

Hi,
  A solution, of course not the best,
--> if i<10, s=msprintf("000%d",i) end
with iteration for high number, or with 3-floor(log10(i)) added zeros?

With $ you write LaTeX expression.

may anybody be able to explain why I get the error message "invalid index in

Maybe because the vector "Energie" is used but not defined so the index 
is not valid.

Re: [Scilab-users] Problem with Matrix operation

Hello,

Le 25/04/2017 à 15:29, SCHULZ Wolfgang a écrit :

Hello,
I want to set certain elements of a matrix to 1. Interestingly the following 
code fills 9 elements with 1. I expected to have only 3 elements (with index 
1,1; 2,2 and 3,3) filled with 1.

A=zeros(5,3)
inx=[1 2 3];
iny=[1 2 3];
A(inx,iny)=1



Using this is for submatrix but what you want is not a submatrix. In 
your special case A=eyes(5,3)




Is there any way to fill a matrix with 1 where I have the indexes in 2 vectors?



IMHO only the for loop works, in general...
