Re: [Scilab-users] output buffer

[antoine . elias]

Hello Jean-Yves,

I tried to reproduce the problem but without success.
Could you give us an example ?

With mine, I generate a file with 8192 lines of 26624 characters.

a = "a":"z";
for i = 1:10, a = a + a;end
length(a) //26624

form = "%s\n";
for i = 1:13, form = form+form;end
length(form) /4 //8192 times "%s\n"

args = list();
args(8192) = a; //alloc list
for i = 1:8191, args(i) = a;end

fd = mopen(fullfile(TMPDIR, "mfprintf.txt"), "wt");

try
tic();
mfprintf(fd, form, args(:));
toc()
catch
end

mclose(fd);

Regards,
Antoine

In other words, how to use "setvbuf" in Scilab? Is there an equivalent
function that works with the mfprintf scilab function?

Re: [Scilab-users] How to convert the ~ input placeholder <= Re: convert matlab code to scilab

[Antoine ELIAS]

Hello,

Or when you have to write a function following a specific prototype ( 
graphic events, optim, ode, ...)


If I would write a function that call another, I have to specify a 
prototype to allow user to call my function.
But in some case, the final user does not need all parameters so he can 
replace unused inputs by ~.

I think that only syntactic sugar.

example:
function for_each(iterable, fn)
    for i=1:size(iterable, "*")
        fn(iterable(i), i, iterable); //item, index, array
    end
endfunction

Users can define fn like this if tthey only need item and don't want to 
use index and whole array

function my_func(a, ~, ~)
    //blabla
end

I don't say that's essential :p
That's my understanding

Hi Samuel,

In fact I've not been using matlab for more than 10 years, so I try to 
understand this as well.


The input tilde is still abit confusing for me as well, I am trying to 
understand its' usage as this page: 
https://octave.org/doc/v4.4.1/Ignoring-Arguments.html


function val = pick2nd (~, arg2)
  val = arg2;
endfunction

I can't see the reason why the input need to ignored in this case, is 
it defined but not being user due to bad user overlooked it? or is it 
neglected and the default value would be used?


Then I find this : 
https://stackoverflow.com/questions/25204074/correct-use-of-tilde-operator-for-input-arguments


*/"The tilde is only for function declaration. Matlab's mlint 
recommends to replace unused arguments by ~. The result is a function 
declared like this function output = MyFunction(a, b, ~, c). This is a 
very bad practice. /**/

/*
*/
/*
*/Since you have a function where the parameters are optional, you 
must call the function with empty arguments 
output=MyFunction(str1,str2,[],[],...,true)."/*


It sound to me that the input tilde is suggested by the matlab mlint 
to improve the code so that the unused variable need not to pass into 
the function, and to improve memory management?


So there are 2 possibilities for the input tilde :

1. used to replace unused variable in the input which defined by user, 
but not being used. So the mlint recomment to replace with tilde, it 
could be be remove possibly due to the project has been calling the 
functions for many time, and changing the 4th to 3rd argument might 
need to change a lot of codes. In this case, the %unused would be good.


2. Tilde used to tell the function to use default value, then 
replacing it with % unused might cause error.


Think we need some x-matlaber to confirm which case.

Thanks again.

Hello Chin Luh,

Thanks a lot for your input.

Both cases -- input and output will have to be converted --, since
the converter is also made to convert (sets of) functions
definitions, not only scripts.

About the input case: Steven's answer is still not really clear to
me. Doing some tests on Octave, we must anyway provide some input
at calling time when  ~ is used as default input in the
definition. AFAIU, this ~ could just be to make sure that no
variable name used inside the function matches the name of the
input argument in the function definition, since "~" alone can't
be actually used as variable's name. In this case, for Scilab, any
input ~ could be replaced with an improbable variable name like
"%unused" or "%kwzxq", and that should do it.

Please, correct me if someone understands something else.

Best regards
Samuel

If you want to be able to specify only the third argument,

specifying [] for the arguments for which the user doesn't

Hello all,

The subject has been already discussed a lot but I would like it to be 
discussed again because I now have a real rationale to promote a 
change in the way complex numbers with small imaginary part are 
displayed.


I don't know if some of you were aware of the clever technique of 
complex-step derivative approximation, but until yesterday I was not 
(see e.g. 
http://mdolab.engin.umich.edu/sites/default/files/Martins2003CSD.pdf). 
Roughly speaking, using the extension of a real function x->f(x) to 
the complex plane allows to compute an approximation of the derivative 
f'(x0) at a real x0 without using a substraction, like in the central 
difference formula (f(x0+h)-f(x0-h))/2/h which is subject to 
substractive cancelation when h is small. In Scilab most operators and 
elementary functions are already complex-aware so this is easy to 
illustrate the technique. For example let us approximate the 
derivative of x->cos(x) at x=%pi/4, first with the central difference 
formula, then with the complex step technique:


--> format("e",24)

--> h=%eps/128, x0=%pi/4
 h  =

   1.73472347597680709D-18

 x0  =

   7.85398163397448279D-01


--> (cos(x0+h)-cos(x0-h))/2/h
 ans  =

   0.0D+00


--> imag(cos(x0+%i*h))/h
 ans  =

  -7.07106781186547462D-01


--> -sin(x0)
 ans  =

  -7.07106781186547462D-01

You can see the pathological approximation with central difference 
formula and the perfect (up to relative machine precision) 
approximation of complex-step formula.


However, the following is a pity:


--> cos(x0+%i*h)
 ans  =

   7.07106781186547573D-01

We cannot see the imaginary part although seeing the latter is 
fundamental in the complex-step technique. We have to force the 
display like this, and frankly I don't like having to do that with my 
students:


--> imag(cos(x0+%i*h))
 ans  =

  -1.22663473334669916D-18

I hope that you will find that this example is a good rationale to 
change the default display of Scilab. To feed the discussion, here is 
how Matlab displays things, without having to change the default 
settings:



>> h=eps/128, x0=pi/4
h =
   1.7347e-18
x0 =
    0.7854

>> (cos(x0+h)-cos(x0-h))/2/h
ans =
 0

>> cos(x0+i*h)
ans =
   0.7071 - 0.i

>> imag(cos(x0+i*h))/h
ans =
   -0.7071

>> -sin(x0)
ans =
   -0.7071

Re: [Scilab-users] Make Variable visible in Scilab from a SCE-script in a toolbox

[Antoine ELIAS]

Hello,

You can use "resume" to return values in caller environment.
In case of callbacks from gui interaction, caller is always "console" scope.

In your callback do something like "data = resume(a);"
That's create or overwrite "data" with the contents of "a"

Example :

xdel(winsid());
clear createGUI callbackFromGui;

function createGUI()
    f = figure(...
    "dockable", "off", ...
    "axes_size", [300 100], ...
    "infobar_visible", "off", ...
    "toolbar", "none", ...
    "menubar_visible", "on", ...
    "menubar", "none", ...
    "default_axes", "off", ...
    "background", color(255, 255, 255));

    uicontrol(f, ...
    "style", "pushbutton", ...
    "string", "Send variable in console context", ...
    "position", [(300 - 200)/2 (100 - 25)/2 200 25], ...
    "callback", "callbackFromGui");
endfunction

function callbackFromGui()
    a = rand(10, 10);
    data = resume(a);
endfunction

createGUI();

After clicking on the button, you should have a "data" variable in the 
console.

Antoine

Re: [Scilab-users] create figure without toolbar, etc

The "bar" with the question mark is the docking system, to allow you to

If you don't want dockable system on your window you can set "dockable"

f = figure("dockable", "off", "toolbar_visible", "off", 
"menubar_visible", "off", "infobar_visible", "off");

Re: [Scilab-users] A gateway example in the current scilab-6.0.1 source still remaining in the scilab 5.5.2 old Scilab C API version.

[Antoine ELIAS]

Hello René,

With Scilab 5.3.0, late of 2010, we have introduce a new API that will 
be compatible with new Scilab 6 environment.
The goal was to depreciate stackx.h interface too dependent on the 
format of the old data storage format. ( called "stack" ).
This interface is defined in Scilab documentation : 
https://help.scilab.org/docs/6.0.0/en_US/section_57c66b650f71d7a7eaca3dfe608a4c08.html
During development of Scilab 6, we worked on a more efficient API: 
https://help.scilab.org/docs/6.0.1/en_US/api_scilab.html


If you want to write gateways and keep compatibility between 5 and 6, 
prefer 
https://help.scilab.org/docs/6.0.0/en_US/section_57c66b650f71d7a7eaca3dfe608a4c08.html
If you want to write for Scilab 6 and more use 
https://help.scilab.org/docs/6.0.1/en_US/api_scilab.html


You can find examples in documentation or in the demonstration toolbox 
'toolbox skeleton' in your Scilab installation folder. 
(SCI/contrib/toolbox_skeleton)

For example the same gateway writes in both API:
--> edit("SCI/contrib/toolbox_skeleton/sci_gateway/c/sci_csum.c"); 
//compatible 5 and 6 version
--> edit("SCI/contrib/toolbox_skeleton/sci_gateway/c/sci_csum6.c"); 
//scilab 6 and more


Thank you for the report, we need to update or remove old examples.
Regards,
Antoine

Dear user or developer experienced in the new Scilab C API,

All the sub-directory: 
scilab-6.0.1/share/scilab/modules/dynamic_link/examples/gateway, 
giving a nice, non-trivial example of a gateway, seems an identical 
copy of the same sub-directory in scilab-5.5.2.


Is there somewhere a version converted for scilab-6.0.1 ?

The conversion does not seem at all obvious to me. For example I 
cannot see how the simple instructions given by: Port to the Scilab 6 
C API, in: Gateways: from Scilab 5 to Scilab 6, could ever make this 
gateway compatible with both the Scilab 5 and 6 APIs. (Is there a 
"mapping" somewhere between the functions, etc, of the old and new 
Scilab APIs as there is between Scilab and Matlab?)


The conversion of that gateway example --- with matrix multiplication 
in C --- would be a far better example to: Getting started with 
API_Scilab, than the rather trivial one given. At any rate as it 
stands the sub-directory in question has no place within the current 
scilab-6.0.1.


Thanks for any comment and maybe the location of an updated version of 
this particular gateway example.

Any idea of what may be going on and how to solve it?

Re: [Scilab-users] Scilab from Powershell

[Antoine ELIAS]

Hello,

I made a quick test and it seems to work ( curiosity ... I never used 
powershell with Scilab )


ps.sce :


PS E:\git\6.0\scilab> $objScilab.SendScilabJob("exec('d:\tests\ps.sce', 
-1);")


   0.3616361   0.4826472   0.5015342   0.6325745

Is it possible that you have an error in your file ?
Do you have try to exec your file in Scilab ?

Re: [Scilab-users] Counter of pointers to an XML object, and clear destructor

[Antoine ELIAS]

Hello Samuel,

In XMLObject there is two levels of reference,
 - one on MList (managed by reference counter)
 - one on internal XMLObject (internally manager like handle, an 
integer that link to a C++ object)


xmlDelete destroy internal XMLObject
clear destroy (unreference and destroy if ref <= 1 ) MList object.

So in your case, after a xmlDelete, the internal XMLObject was destroyed 
but not the MList.
And after a clear doc, the MList was destroyed but the internal 
XMLObject not.


Current XMLObject is based on simple MList with the id of the doc ( 
store as double ).
If we want to correctly destroy the internal XMLObject with the clear 
command.
We must change the implementation to use types::UserType instead of 
types::Double and uses destructor of UserType to free XMLObject.


> Deleting an object should clear all its pointers. For instance, with 
the XML example

> hereabove, deleting the document should clear doc and doc2.
I am not agree with that, I cannot delete an user variable indirectly. ( 
xmlDelete(doc) that will delete doc )

Only clear command can do that. For me it will be a bad practice.

Antoine
Le 28/07/2018 à 16:20, Samuel Gougeon a écrit :

Hello,

I am doing some tests about the save() function, in order to document 
its behavior when saving pointers to some objects.


There is the case of XML objects:
Contrarily to graphic handles, that are pointers whose reloading 
restores the pointed graphics, saving XML pointers is possible, but 
then their reloading does NOT restore the XML document.
Then, when digging in Bugzilla in order to search for features about 
this and the clear() function applied to XML pointers, i've found back 
the following comment from Calixte 
, referring to an 
expected change of Scilab 6 with respect to Scilab 5:


/With Scilab 6, things will be easier since each data will have a 
reference counter [of pointers to it] which will allow to call a kind 
of destructor when the reference count will be zero.//

/
In practical, this new feature looks still not to be implemented. Here 
is an illustration:


// Let's create an XML document and a pointer "doc" to it:
--> doc = xmlReadStr("rib=""bar"">Hello")

 doc  =
XML Document
url: Undefined
root: XML Element

// Now, let's make a copy of the pointer:
-->doc2=doc
 doc2  =
XML Document
url: Undefined
root: XML Element

--> doc2==doc
 ans  =
  T T    <<< this double True is strange, but it's not the matter here

// Then let's clear both pointers: If a counter actually exists,
// it shall be set to 0 afterwards.
// And if the automatic destructor is implemented, then this should
// automatically delete the XML document. What's the reality?:
--> clear doc doc2   // OK
-->  xmlGetOpenDocs()
 ans  =
   ans(1)
XML Document
url: Undefined
root: XML Element

The document still exists. So, the automatic destructor is not yet 
implemented,

at least for XML objects.

Is it a pity? To me, the reverse approach would be more relevant:
Deleting an object should clear all its pointers. For instance, with 
the XML example

hereabove, deleting the document should clear doc and doc2.
It's unfortunately not the case:
--> xmlDelete(xmlGetOpenDocs()(:))  // cleaning the area
--> doc = xmlReadStr("rib=""bar"">Hello");

--> doc2 = doc;
--> xmlDelete(doc)
--> isdef(["doc" "doc2"],"l")
 ans  =
  T T
--> doc
 doc  =
-->

This is the same issue with graphic handles when the figure they point 
to has been closed:
We then get some still existing /but invalid/ handles, instead of 
properly clearing them.


Regards
Samuel

Re: [Scilab-users] ATOMS error (Scilab 6.0.1)

Hello all,

Just recently been getting this error when running the ATOMS module manager:

"No ATOMS module is available. Please, check your Internet connection or
make sure that your OS is compatible with ATOMS."

I am using version 6.0.1 and know that it was working a while back, so not
sure what has changed. It can clearly get to the repository to update the
database, but then generates an error. Console shows: "Scanning repository
http://atoms.scilab.org/6.0  ... Done"

I also verified this on a separate machine that I only recently updated with
6.0.1, and that gave the same response. Not a big deal as I tend to write
functions as I need them, but seems odd.

Tried deleting the user folder at:
C:\Users\\AppData\Roaming\Scilab\scilab-6.0.1 but did not help.

Any ideas? It works fine under 5.5.2.

Re: [Scilab-users] File exist function?

Hello Claus,

You can use "isfile" function to check existence if a file and "isdir"

Dear Scilabers

I wish to check for the existence of some files. For this I created a 
simple function:


[out]=function  file_exist(fname)
 [fd,  err]  =  mopen(fname);  // Try to open file, mode: 
'br'(binary-reading)
 if  err==0  then
 out=%t;
 mclose(fname);
 else
 out=%f
 end
endfunction

I didn't check, but presumably this would work.

Is such a function already available? Which way is the "official" way 
to do this in Scilab?


Maybe I'm searching for the wrong word, but I found some ways in 
Scilab. The "fileinfo" seems to be the closest one to what I wish to do.


Matlab has a function "exist()" which can check for files too. Scilab 
has the function "exists()" - notice the function name is plural, not 
singluar - and this one AFAIK only works for Scilab variables (not 
files), although I didn't check.


If fileinfo is the right way, maybe an example for the help could be 
to make a file_exist function, to show ... (?) ... when I search for 
Scilab file exist function, I'm not guided in any 
specific way/direction and find myself insecure whether I find the 
right help.

dependent dlls also located in SCI/bin are not found by dependency walker.
So, it seems that the scilab installations on which the dll can be loaded
find the scilab dlls in SCI/bin, but those which cause an error don't find
them. Any ideas what I can do instead of copying all dlls from the SCI/bin
folder to the folder where my dll is?

For compilation of Scilab, we provide Visual Studio 2013 solution.
For compilation of toolbox/code, you can use VS2010, VS2012, VS2013 and

Scilab 6 on Windows provides Visual C++ redistributable 2013.
So for better compatibility/portability, I suggest you use VS2013 ( Pro

(https://www.microsoft.com/en-us/download/details.aspx?id=48145)

Scilab 6 beta 2 provides only VS 2013 runtime libraries

At Scilab start, call findmsvccompiler() to get version that Scilab 
found.
If VS 2013 pro is found (msvc120pro [1]) , Scilab always use it to avoid 
compatibility trouble.
You can force Scilab to use another MS compiler by setting environment 
variable "SCILAB_PREFERED_MSVC" ( with misspelling ^^ )


setenv("SCILAB_PREFERED_MSVC", "msvc140pro"); //to set VS 2015 pro as 
c/c++ compiler

Re: [Scilab-users] Scilab 6.0 Beta 2 - Load/save bug

[antoine . elias]

Hi guys,

Scilab 6 can load data from Scilab 5 if data were saved as SOD files

In Scilab 5 :
a = 1;
save(home + "/myfile.sod", "a"); // use "" on variable to save in SOD 
format instead of old format.


In Scilab 6 :
load(home + "/myfile.sod");
a == 1

Re: [Scilab-users] Invalid index?

[antoine . elias]

Hello,

Confirmed, failed on Scilab 5.5.2 but works in Scilab 6 beta 1

You can do that to by pass the problem :

god.vars = [];
for i=1:11
disp(i);
god.vars = [god.vars, uicontrol(god.frame1, 'style', 'text', 
'string', god.labels(i), 'position', [i*60 - 8 + fudge, 30, 10, 20 ])];

end

or

for i=1:11
disp(i);
uicontrol(god.frame1, 'style', 'text', 'string', god.labels(i), 
'position', [i*60 - 8 + fudge, 30, 10, 20 ]);

end

god.vars = god.frame1.children;



Le 2016-03-30 15:48, scilab.20.browse...@xoxy.net a écrit :

This one has me baffled!

If I run this code:
...
god.vars = [];
for i=1:11
disp(i);
god.vars(i)  = 1; // uicontrol( god.frame1, 'style', 'text',
'string', god.labels(i), 'position', [ i*60 - 8 + fudge, 30, 10, 20 ]
);
...
end

It completes without error.

But if I uncomment the uicontrol:

god.vars(i)  = uicontrol( god.frame1, 'style', 'text', 'string',
god.labels(i), 'position', [ i*60 - 8 + fudge, 30, 10, 20 ] );

The assignment to god.vars(i) works when i == 1;, but fails when i ==
2 as follows:

-->exec('C:\test\poly.sce', -1)

1.

2.
god.vars(i)  = uicontrol( god.frame1, 'style', 'text', 'string',
god.labels(i), 'position', [ i*60 - 8 + fudge, 30, 10, 20 ] );

!--error
21
Invalid index.
at line  43 of exec file called by :
exec('C:\test\poly.sce', -1)

I've eliminated the only other index usage (god.labels(i)) as a 
problem;


so why can it assign to god,vars(1) and not to god.vars(2)?

Thanks Buk.

Re: [Scilab-users] How to replicate what "load" does (aka creating variable in the current workspace from inside a function)

[antoine . elias]

Hi users,

Just to explain, why "who" change.
Previous implementation of "who" was stack dependant, so when you ask 
local variables names,
Scilab 5 reads the stack from bottom to top ( or the opposite ), and 
returns list of variables it found.


Now in Scilab 6, we have remove this stack ( i'm sure you already know 
that ^^ ).

And we use map to store local variables names.
maps are pretty fast but do not ensure order of elements.
"who" returns a list of local variables names, that's all.

The alphabetical order is a side effect of implementation like creation 
order was in Scilab 5.
If we use another system to store local variables names, we can get 
another output.


So please, do not use "alphabetical" order without "sorted" argument. It 
may change in future.



Antoine
ps: I'm pretty sure that "who"'s help page does not say "'who' returns 
variables names in creation order."


Le 2016-02-22 12:51, Antoine Monmayrant a écrit :

Not sure if it is related to `who` or to the special use of `resume`.


I can confirm that it comes from the bug in who for scilab 6.0.
See also my solution that uses 'resume' and not 'who' and work in both
5.5 and 6.0

Cheers,

Antoine

Re: [Scilab-users] Help write simple GUI

[Antoine ELIAS]

Hi Claus,

For small dialogs to ask inputs, use *x_mdialog* function ( 
http://help.scilab.org/docs/5.5.0/fr_FR/x_mdialog.html )

function result = compute_voltage()
txt = ['Power (Watt)';'Impedance (ohm)'];
values = *x_mdialog*('System values',txt,['100';'8'])
if values  [] then
w = values(1);
o = values(2);
w = eval(w);
o = eval(o);

if typeof(w)  constant | int(w)  w | typeof(o)  constant | 
int(o)  o then
error(bad value, integer values expected);
end

result = sqrt(w * o);
else
result = [];
end
endfunction

voltage = compute_voltage()

Le 31/05/2014 22:01, Claus Futtrup a écrit :
 Hi there

 I hope someone can help me make a simple GUI front end to my script, 
 preferably without using GUI Builder or guimaker, because I think I'll 
 understand better without using additional tools.

 The GUI - a window containing two variable input:
 1. text + input box + text
Again the input is a number, typically an integer (as in system power : 
 100 Watt). 100 being the user variable input.
 2. text + input box + text
A number, typically an intereger (as in impedance : 8 ohm). 8 being the 
 user variable input.

 The script will then based on 100 Watt into 8 ohm calculate the voltage = 
 sqrt(100*8). I will round the number to one decimal, convert it to a string 
 and create an answer, like Input level : 28.3
 Volt.

 The GUI should contain two buttons, e.g. an OK + a QUIT button. The OK button 
 runs the calculations. The quit button quits the script (may as well quit 
 Scilab).

 I've studied the GUI controls in Scilab already and I understand the the old 
 way of making a new window is:

 f = figure();

 but it seems there's a new command in Scilab 5.5.0:

 f = createWindow();

 The new method probably has its advantages, but the Scilab manual doesn't 
 really explain... can anybody explain to me?

 Can you use the same uicontrol commands with both methods? (can I use 
 examples found on the internet using figure and just replace figure with 
 createWindow?). It seems to me that the examples in
 the createWindow gives uicontrol some inputs named units - normalized - 
 etc. - which are not present when looking at old figure() examples.

 My next question will be, how do I create a uicontrol which accepts a string 
 input (as I need 2 of those). The uicontrol documentation says the Edit 
 style will do that. Funny, but also a bit
 strange, that you can find all sorts of examples for using uicontrol with 
 checboxes, listboxes, radiobuttons, pushbuttons, tables etc. - but no 
 examples are provided with this most useful editable
 string input ... (???)

 ... hereafter I expect to evaluate the two strings (or if they're returned as 
 numbers, that's fine of course, I just don't need the script to crash if 
 something is not right). Then execute my code.

 Best regards,
 Claus

Re: [Scilab-users] Converting a matrix of string into real

[Antoine ELIAS]

You can use msscanf function too
http://help.scilab.org/docs/5.4.0/en_US/mfscanf.html

sample :

//your data
dataIn = string(rand(500,500));
typeof(dataIn)
size(dataIn)

//convert to double
tic();
dataOut = matrix(msscanf(-1, dataIn, %f), size(dataIn));
disp(convertion time :  + string(toc()));
typeof(dataOut)
size(dataOut)
