Subject: [Scilab-users] Defining own blocks, labeling super blocks
Message-ID: <CAMhHKZcKuKTaZhnv9DhGHXBiRJPAzaT1hQfSC4Vi4mvhkzGJCA@mail.gmail.com>

Hello,

I searched about labeling superblocks and I found this post in the mailing
list:
http://mailinglists.scilab.org/Scilab-users-Xcos-names-labels-for-subsystems-and-ports-td4033970.html,
but I didn't find a tutorial which shows how I can create own blocks, so I
would ask if somebody has a good tutorial? Do I have to create my own block
by code or is there a possibility to label the inputs and outputs in xcos?

https://www.scilab.org/community/scilabtec/2011/User-defined-blocks-in-Xcos
In this link I found a description with skeleton. But there is less
description in it how they customized the superblock ( by code or in xcos?).

Best regards,

Martin

Subject: [Scilab-users] Question about expm function
Message-ID: <CALTEAJiV_zzHYmT4=zNOSuQudwf3NoHsk6vaZruOHJ1mL0PwYg@mail.gmail.com>

Hi,

I am trying to use expm() and do not get what I am expecting.

I enter A = [1,0.5,0.7;0.3,0.7,1;1,0,1]
and B = expm(A)
and get as result

B =

    4.1672519    1.3854159    2.8881517

    2.1672628    2.4007931    3.0513947
    3.1716359    0.6680066    3.96685.

I expected the matrix B elements to be exponents of corresponding elements
of matrix A. For example
B(1,1) = B(2,3) = B(3,1) = B(3,3) = 2.7182818

Could you please explain to me what is going on?

Thanks

Jean

Hello,

The matrix exponential is defined as

expm(A)=I+A+1/2*A^2+...+1/k!*A^k+...

where the "*" denotes the matrix product.

You can obtain what you wanted with

exp(A)

i.e. element-wise exponential of A

Hi, i am having problems with the below code (file attached).

The function call appears to return the correct differences(Z), but 
falls over at the leastsq call to optimize const.
I understand what the error is implying and have solved similar 
instances many times before, but not this one!

Any help or advice would be very much appreciated.

They are several problem in your code

-  First of all  as you pass vr,vs and x by the context, x is redefined 
some where in the leastsq function
    to avoid the problem you must define fun1 as follow
    function [z]=fun1(const,vr,vs,x)
        ...
    endfunction

    and call leastsq with
    [f,ans] = leastsq(list(fun1,vr,vs,x),const0)
- second
   for some value of const the value returned by fun1 is complex (it 
seems tht the imaginary parts are zeros so adding z=real(z) at the end 
of fun1 solves the problem.

Hello Daniel

 

I?ve already met your problem one year ago, and for me it is really a bug.

 

I work with scilab x64 5.5.2, netbeans 7.01, on W7 or W10 platform.

 

I?ve sovled it in my application, so I?m just able to propose parts of code.

 

I?ve delay the 2 instructions Scilab sci = new Scilab(true)  and if (sci.open()) {, by creating a ScilabManager class, ? and a thread class named  Idle

 

Part of ScilabManager  (also note the  public static void OpenScilab())

 

public class ScilabManager {

    

    public static Scilab sci;       //Driver Scilab

    public static boolean bScilabOpen;

    public static boolean InitScilab;   

 

    public  static Fifo FifoScilab;

    private static TListeFifo SciJob;

 

    static ScilabError TErrorScilab;

 

    public static File ScilabFile;

 

    private static int dim = 500;

    public static String [] Script;

    private static int iScript;

    

    public static Configuration AppConfiguration;  

    public static Log LogScilab;  

    

    public static int NumGraph=0;

 

 

    ScilabManager() {

        try {

            sci = new Scilab(true);

            InitScilab=true;

            

       } catch (JavasciException.InitializationException ex) {

            Logger.getLogger(ScilabManager.class.getName()).log(Level.SEVERE, null, ex);

        }

                

        

    }

    

    @SuppressWarnings("CallToThreadDumpStack")

    public static void OpenScilab() {

        

        

        try {

            

            bScilabOpen=sci.open();

            

        } catch (JavasciException ex) {

            ex.printStackTrace();

        }

        

        if (bScilabOpen) System.out.println("\nScilab est ouvert\n");

            else System.out.println("\nErreur ouverture Scilab\n");       

        

        ScilabError.ClearScilabError();       

        

        try {

            // Initialisation et chargements des fonctions Scilab

            //---------------------------------------------------

            AppConfiguration = new Configuration();

        } catch (FileNotFoundException ex) {

            Logger.getLogger(ScilabManager.class.getName()).log(Level.SEVERE, null, ex);

        } catch (IOException ex) {

            Logger.getLogger(ScilabManager.class.getName()).log(Level.SEVERE, null, ex);

        } catch (JavasciException ex) {

            Logger.getLogger(ScilabManager.class.getName()).log(Level.SEVERE, null, ex);

        }

        

        try {

            // Initialisation du fichier de log out (Traces commandes Scilab)

            //--------------------------------------------------------------

            LogScilab = new Log();

            OptsimView.SetLogFile();

        } catch (FileNotFoundException ex) {

            ex.printStackTrace();

        } catch (IOException ex) {

            ex.printStackTrace();

        }       

        

        Script = new String[dim];

 

Now note part of Idle task :

 

public class Idle extends Thread  {

    

    protected volatile boolean IdleRunning = true;

    public static boolean bCloseIdle=false;

    

    private static int Count=1;

    private static int setGraphe=0;

 

 

    private static JTextField TF=null;

    private static Timer bTimer;

    private static JLabel AnimationLabel;

    private static Icon idleicone;

 

    private int ThreadNumber;

 

 

    Idle (JTextField TFi, Timer busyIconTimer,

          JLabel statusAnimationLabel, Icon icone) {

            TF=TFi;

            bTimer=busyIconTimer;

            AnimationLabel=statusAnimationLabel;

            idleicone=icone;

            this.ThreadNumber=Count++;

    }

 

  @Override

  public synchronized void run() {

      

    boolean bTest;

    

    if (ScilabManager.InitScilab) {

        

            ScilabManager.OpenScilab();

    }

    

    ScilabManager.sci.exec("aPPeScilabJavasciv2=1;");    

 

    

    while (IdleRunning) { ?etc

 

So instructions Scilab sci = new Scilab(true)  and if (sci.open are delayed.

 

This is the only solution I?ve found. After that Scilab well run with Java netbeans and javasci2.

 

Also well note that my program doesn?t work with Scilab 6.0.0 b2 at compile time and see :

 

 

http://bugzilla.scilab.org/show_bug.cgi?id=14626

 

Hope it helps you

 

Sincerely

Pierre

Objet : [Scilab-users] Question about javasci V2

 

Hi, I am using Scilab 5.5.2 and trying to open a Scilab script from
Java. Therfore I followed the documentation: Compute and run with javasci v2.

I use Eclipse to compile and run. It works, but I want now to open it in "advanced mode"  to get grahpics
(Scilab sci = new Scilab(true);). If i do it, I get a compile Error. What's wrong ?
Code and Error Plot out see below.

Thank You for your Help,
Daniel Neutzler

Subject: [Scilab-users] ffilt Description
Message-ID: <6F5A9736AF0F75478BDC0405E26493249FD14A@CHN-SV-EXMX02.mchp-main.com>

Hi.

Is there someone out there with more details/understanding about
the filter design done by the ffilt command?
Specifically, for example, if one does


x=ffilt("lp",5,0.1)


n  the five coefficients are obviously not for a simple "boxcar" filter.

Is this a butterworth design? Is there a reference for what this

command is actually implementing?

n  What is the definition of the cutoff frequency for ffilt?

If you take the above example and

[a,b] = frmag(x,500);

plot (a)

the first zero of amplitude is around 222 Hz, but the

0.1   cutoff frequency would be at 100 Hz for 1000Hz sampling.
Is the cutoff frequency defined as ln(2) of the DC response?

n  Why are the coefficients not normalized to give

a DC response amplitude of 1? Isn't that the standard

approach for filter design?

Thanks in advance.
G

Message-ID: <AM4PR0701MB2161B8B50E97E7BB3CDD5F0EE5420@AM4PR0701MB2161.eurprd07.prod.outlook.com>

Hello,

I probably missed something obvious but here is my trouble :
I have a vector a = 1:6
and want to locate b = [2 3 4] inside a (the result being 2).

So I know members() which locate any of the elements of b inside a
and vectorfind() which can search a vector inside a matrix.

I searched the archive of the list and found topics about Matlab ismember()
and locating a phrase in a text.

But none of these are convenient.

As my vector is rather small, I can do

aa = [a(1:$-2)  ;  a(2:$-1) ; a-3:$)]

vectorfind(aa, b, "c")

but I wonder if there is a better (vectorised) solution?

Regards

Hello Christophe,

Having the same need, i have recently implemented a vectorized solution, 
by the way truly extended to hypermatrices (up to now only the first 
page of hypermatrix was considered and searched in).

I am posting it on the CodeReview. I still need a bit of time to update 
the help page. It shall be available in 6.1, but you can download and 
use it from the codeReview (will post the URL here just after commiting).

Cheers
Samuel

Here is a sample with a matrix, and its results.
I ended up with hypermatrices. You can test it.

  ans  =
    2.

This is a SEP :)
Any comments are welcome.

OK, so I didn't miss anything (-:

Thanks for sharing your code, I'll have a look at it.

Subject: [Scilab-users] problems installing modules
Message-ID: <1486631137210-4035457.post@n3.nabble.com>

Hello! 
I have a problem and I don't know how to solve it. When I executed Scilab
this message appears. I have just installed the 5.5.2 version for OSX. 

atomsLoad: The file
'/Applications/scilab-5.5.2.app/Contents/MacOS/share/scilab/contrib/quapro/1.1.1/loader.sce'
from (quapro - 1.1.1) does not exist or is not read accessible. 

And the problem is that I cannot execute some commands that I need (I
installed the modules 'stixbox' and 'grocer' using the command
atomsInstall('stixbox') and the same with the other one. 

Does anyone know how to solve this problem? 

Thanks!

Hello!
In may first exercises with SCILab functions I was disappointed that
I cannot see the variables declared and used in the function with Variable
Browser.

I tried the global statement, but I cannot browse the global variables in
the usual way.

Is there a way to have all variables public?

Thank you

Hi all,

I'm developing a 'modeling tool' for easing optimisation in Scilab: the 
Sopi toolbox <https://atoms.scilab.org/toolboxes/sopi/0.1.2>

At the moment, it supports (dense) linear optimisation problems and I 
have added the examples from

https://wiki.scilab.org/Linear%20Programming%20Examples%20in%20Scilab

in the demos.

I am quite interested in some feedbacks if you have any.


Best regards,

What exactly do you want?

Are you trying to modify global variables from within a function?

Are you trying to pass values from the function to the outside world?

Are you trying to use (but not modify) global variables from within a
function?

Or do you disagree with the way that the variable browser displays
variables?

Sorry -- just re-read your question and realized what you actually
meant.

I just double-checked this -- if you hit a breakpoint inside a
function, the variable browser shows that functions variables. ?Once
you exit the function, the variables that only exist within the
function disappear.

I work with scilab on xubuntu and i have a little problem...Although i had

coding but i'm trying.The problem is that scilab doesn't recognize dft()
function while other functions like fft() or convol() or syslin() are 
recognized .I had searched everywhere for that but everywhere i look it says
that dft() is a given function and i don't know what to do!!! Any help??

Scilab 5.4.1 was the last Scilab function including dft(). This function 
was removed from Scilab 5.5.
fft() does the same. Please see the last example of the fft() help page.

Subject: [Scilab-users] function with more result variables, how?
Message-ID: <1486938857336-4035470.post@n3.nabble.com>

Hello!
I declared a function
e.g.
function [ DifT, FByReal, FR ] = MyXYZ(koeff)
DifT = 33.0; FByReal = [ 1.0 , 55.7 ]; FR = [ 1 2 3; 4 5 6; 7 8 9; 10 -11
-12 ];
endfunction

but only the first result is delivered.

In help: <lhs_arguments> stands for the output argument list.

How to have more result variables with different type*?*

Thank you
Erhy

I get:
--> function [ DifT, FByReal, FR ] = MyXYZ(koeff)
   >     DifT = 33.0;
   >     FByReal = [ 1.0 , 55.7 ];
   >     FR = [ 1 2 3; 4 5 6; 7 8 9; 10 -11 -12 ];
   > endfunction

--> [a,b,c] = MyXYZ(1)
  c  =
    1.    2.    3.
    4.    5.    6.
    7.    8.    9.
    10.  -11.  -12.

  b  =
    1.   55.7

  a  =
    33.

All is right.

Hello Pierre,

Just a remark: you may want to make Sopi available for Scilab 6.0 (you 
can download a nightly build 
<http://www.scilab.org/en/development/nightly_builds/branch60>).
"-->exec builder.sce" yielded an error on function save() as it takes 
strings as arguments now.

Best regards,
Paul

Hi Paul, 

You are right, given the timing, this seems to be a good idea to make it
work on Scilab 6.0. I'll do that. 

Thank you, 

Best regards, 

Pierre

Hello Pierre,
thank you for your answer. It is nice to hear that my Problem is 
probably a Bug.
I'm not sure how to use your example. Which Libs do I need for it or may 
you have a simple example to use it?
I'm sorry, my Java knowlegde is restricted (Beginner).

Thank You for your Help,
Daniel Neutzler

Hi Scilab users,
I would like to install only a C/C++ compiler for Mac OS Sierra. I had installed Xcode, but it was very heavy (about 4.5GB) for the SMD disk in my MacBook Air. I'd like to install Eclipse IDE C++ to program C/C++, but I think it requires a C/C++ compiler, doesn't it?
Thank you in advance.
Best,Reinaldo.

Hello Reinaldo,

You don't have to install the whole Xcode to have gcc (pointing to 
clang) available, you can simply install the command-line tools 
<http://www.mkyong.com/mac/how-to-install-gcc-compiler-on-mac-os-x/>.

Regards,
Paul

Something like

plot(course(Ixs))

axis = gca();

axis.data_bounds(1, 1) = 1;

axis.data_bounds(2, 1) = size(course, "r");

"X axis redimensioned to 1": Do you mean: ranging from 0 to 1, or plotting a single component (=> which kind of plot? With a marker?), or..?

Hello Samuel,
Christophe's method is nearly acceptabel for me,
so you see what I mean.

But  I miss the value with index 9 in the plot modified by Christophe's
method.

I caught it: you meant "X axis redimensioned to (1:size(course,'r')) !
Why not simply
plot(course)
??
It ranges from 1 to 10.

Please ignore this. You wish plot(course(Ixs)) not plot(course).

And with

clf
plot(Ixs,course(Ixs))
ax  =  gca();
ax.data_bounds(1:2)  =  [1  length(course)];

?

Thank you Christophe ans Samuel*!*
it works!

Between my experiment*:*
coursePn = ones( course ) .* %nan ;
coursePn( Ixs ) = course( Ixs ) ;
plot( coursePn , 'r*') // but without lines between the points

Hi Reinaldo and welcome,

Yes Paul is right and just for completness (and CC-ing dev) :

We  currently do not require an IDE to build Scilab ; you can program using vim / emacs / notepad++,
gcc / clang / msbuild. As common IDEs provide a way to import an exiting code base as a new project,
we also do not provide project files (other than the VisualStudio ones required by msbuild).

PS: I personally use Netbeans and/or Eclipse JDT for Java programming. Eclipse CDT and/or Vim (with
YouCompleteMe) for C/C++ programming.

Hello Daniel,

 

Here is a basic program I?ve realized under netbeans 7.01

It works with scilab x64 windows 7 or 10, scilab 5.5.2 ; not with 6.0.0 b2

 

Also here are the libraries to incilude in your java project (eclipse if i well understood) :

 

org.scilab.modules.jvm.jar

org.scilab.modules.javasci.jar

org.scilab.modules.core.jar

org.scilab.modules.types.jar

JDK1.8

 

It works with jdk1.8.0_40

Hello Pierre,
thank you for your answer. It is nice to hear that my Problem is probably a Bug.
I'm not sure how to use your example. Which Libs do I need for it or may you have a simple example to use it?
I'm sorry, my Java knowlegde is restricted (Beginner).

Thank You for your Help,

Hello Daniel

 

I?ve already met your problem one year ago, and for me it is really a bug.

 

I work with scilab x64 5.5.2, netbeans 7.01, on W7 or W10 platform.

 

I?ve sovled it in my application, so I?m just able to propose parts of code.

 

I?ve delay the 2 instructions Scilab sci = new Scilab(true)  and if (sci.open()) {, by creating a ScilabManager class, ? and a thread class named  Idle

 

Part of ScilabManager  (also note the  public static void OpenScilab())

 

public class ScilabManager {

    

    public static Scilab sci;       //Driver Scilab

    public static boolean bScilabOpen;

    public static boolean InitScilab;   

 

    public  static Fifo FifoScilab;

    private static TListeFifo SciJob;

 

    static ScilabError TErrorScilab;

 

    public static File ScilabFile;

 

    private static int dim = 500;

    public static String [] Script;

    private static int iScript;

    

    public static Configuration AppConfiguration;  

    public static Log LogScilab;  

    

    public static int NumGraph=0;

 

 

    ScilabManager() {

        try {

            sci = new Scilab(true);

            InitScilab=true;

            

       } catch (JavasciException.InitializationException ex) {

            Logger.getLogger(ScilabManager.class.getName()).log(Level.SEVERE, null, ex);

        }

                

        

    }

    

    @SuppressWarnings("CallToThreadDumpStack")

    public static void OpenScilab() {

        

        

        try {

            

            bScilabOpen=sci.open();

            

        } catch (JavasciException ex) {

            ex.printStackTrace();

        }

        

        if (bScilabOpen) System.out.println("\nScilab est ouvert\n");

            else System.out.println("\nErreur ouverture Scilab\n");       

        

        ScilabError.ClearScilabError();       

        

        try {

            // Initialisation et chargements des fonctions Scilab

            //---------------------------------------------------

            AppConfiguration = new Configuration();

        } catch (FileNotFoundException ex) {

            Logger.getLogger(ScilabManager.class.getName()).log(Level.SEVERE, null, ex);

        } catch (IOException ex) {

            Logger.getLogger(ScilabManager.class.getName()).log(Level.SEVERE, null, ex);

        } catch (JavasciException ex) {

            Logger.getLogger(ScilabManager.class.getName()).log(Level.SEVERE, null, ex);

        }

        

        try {

            // Initialisation du fichier de log out (Traces commandes Scilab)

            //--------------------------------------------------------------

            LogScilab = new Log();

            OptsimView.SetLogFile();

        } catch (FileNotFoundException ex) {

            ex.printStackTrace();

        } catch (IOException ex) {

            ex.printStackTrace();

        }       

        

        Script = new String[dim];

 

Now note part of Idle task :

 

public class Idle extends Thread  {

    

    protected volatile boolean IdleRunning = true;

    public static boolean bCloseIdle=false;

    

    private static int Count=1;

    private static int setGraphe=0;

 

 

    private static JTextField TF=null;

    private static Timer bTimer;

    private static JLabel AnimationLabel;

    private static Icon idleicone;

 

    private int ThreadNumber;

 

 

    Idle (JTextField TFi, Timer busyIconTimer,

          JLabel statusAnimationLabel, Icon icone) {

            TF=TFi;

            bTimer=busyIconTimer;

            AnimationLabel=statusAnimationLabel;

            idleicone=icone;

            this.ThreadNumber=Count++;

    }

 

  @Override

  public synchronized void run() {

      

    boolean bTest;

    

    if (ScilabManager.InitScilab) {

        

            ScilabManager.OpenScilab();

    }

    

    ScilabManager.sci.exec("aPPeScilabJavasciv2=1;");    

 

    

    while (IdleRunning) { ?etc

 

So instructions Scilab sci = new Scilab(true)  and if (sci.open are delayed.

 

This is the only solution I?ve found. After that Scilab well run with Java netbeans and javasci2.

 

Also well note that my program doesn?t work with Scilab 6.0.0 b2 at compile time and see :

Hope it helps you

 

Sincerely

Objet : [Scilab-users] Question about javasci V2

 

Hi, I am using Scilab 5.5.2 and trying to open a Scilab script from
Java. Therfore I followed the documentation: Compute and run with javasci v2.

I use Eclipse to compile and run. It works, but I want now to open it in "advanced mode"  to get grahpics
(Scilab sci = new Scilab(true);). If i do it, I get a compile Error. What's wrong ?
Code and Error Plot out see below.

Thank You for your Help,
Daniel Neutzler

Subject: [Scilab-users] Scilab 6 Release
Message-ID: <58A4716F.9070506@scilab-enterprises.com>

Dear Scilab users,

We are very happy to announce the release of Scilab 6.0.0.

The Scilab Team invested significant development efforts for the past 
years in order to release Scilab 6.
The goal with Scilab 6 is to address technological evolutions and new 
needs in terms of modeling and simulation from the scientific & 
engineering community.
This led our team to completely redevelop the computation core of Scilab 
in order to build a solid base combining performance and evolutivity.
The new aspects of Scilab 6 worth notifying are the following:

  * New language parser & new core,
  * New utilities for development productivity,
  * Xcos block diagram improvement,
  * Newsfeed - a communication channel with the users

Download it on Scilab.org <http://www.scilab.org/>

Scientifically yours

-- 

The Scilab Team

Message-ID: <63ec49fa-ad8f-d4af-cb44-563eb902d29e@haw-hamburg.de>

Hello Pierre,
I understand your Example. I can run it if I change it to Scilab sci=new 
Scilab(false) without graphics.
How do I use the thread class Idle and the ScilabManager Class with the 
Example to make it run ?

Like that ?
...
public class Main {
     static boolean bgraph;
     public static void main(String[] args){
*Idle newThread= new Idle(???);
     Idle.run();
*    ...further with your Example

Moreover my compiler dosen't know types /classes in  Idle and Scilab 
Manager. Which imports/librarys do I need ?

Thank You So Much,
Daniel

Subject: [Scilab-users] About some changes in Scilab 6
Message-ID: <4da87406-ca3a-f371-2e3b-d71e0d7d5e96@pierre-vuillemin.fr>

Hi all,

Congratulations to Scilab team for the release, it looks very promising!


I have begun to test the compatibility of some of my tools with Scilab 6 
and I have some questions:

    - the way libraries are handled seems to have changed with Scilab 6,
    and the example provided in 'help lib' does not work anymore,

        //define some functions
        function z=myplus(x, y)
           z = x + y
        endfunction

        function z=yourplus(x, y)
           x = x - y
        endfunction

        //create the *.bin files in libdir
        libdir = TMPDIR;
        save(libdir + '/myplus.bin', 'myplus');
        save(libdir + '/yourplus.bin', 'yourplus');

        //create the name file
        mputl(['myplus';'yourplus'],TMPDIR+'/names');

        //build the library containing myplus and yourplus
        mylibfoo = lib(libdir+'/');

    The above code says that the path is not a path to a valid library.
    Could someone explain what 'lib' is expecting? (I would like to
    avoid using 'genlib' as it does not recursively goes through
    subdirectories).


    - when 'error' is called within a function that overload the
    behaviour for some object, then the error message is not displayed, e.g.

        a = mlist(['myType']);
        function %myType_e(varargin)
            error('My error msg')
        endfunction
        a(1)


    only says that the operation is not defined for this type without
    displaying 'My error msg'.


    - I'm not sure that this is specific to Scilab 6, but I've noticed a
    large difference in performance for solving linear systems A*x = b
    in comparison to Octave and Matlab. For instance,

        n = 100;
        N = 1000;
        T = 0;
        for i = 1:n
            A = rand(N,N);
            b = rand(N,1);
            tic();
            x = A\b;
            T = T + toc();
        end
        disp(T/n)


    is (significantly) slower with Scilab (binaries for linux 64bits)
    than with Octave. Is it due to the way the underlying lapack library
    is compiled?


    - In Scilab 5, given a variable 'x', the expression

        x = clear('x')


    was allowed and would clean the variable 'x'. Used together with
    'resume' in a function, that allowed to clean variables from the
    above environment. While it might not be a very safe coding
    practice, is there a way to reproduce this behaviour in Scilab 6 ?

Hello Pierre,

That's right. The changes about the library generation was emphasized on 
the forum on 2015 summer (please see here 
<http://mailinglists.scilab.org/lib-unavailable-on-YaSp-tp4032576p4032578.html> 
for instance).
By the way, even before these changes, the example shown in the lib page 
is awful. The only proper way to build a library is using genlib(). This 
example is clearly outdated.

So, it is time to try using tbx_make() with proper flags.

This is because the prototype of a extraction overload for A(i1,i2,..,iN) is
function R = %typeOfA_e(i1,i2,...,iN,A)
The last input argument is the object from which you want to extract 
some component.
If you specify varargin, varargin is a list(), and so you get the given 
error message.

Did you benchmark and compare Scilab 5.5.2 an Scilab 6.0.0 performance 
for this example?

Actually, it was formerly possible to delete a variable by assigning a 
null variable to it.
And primitives without output arguments -- like clear -- returned such 
an object of type==0.
But the definition and the management of objects of type==0 have 
actually changed. In my opinion, the new management is not yet mature. I 
am updating the type() help page 
<https://codereview.scilab.org/#/c/19105/>, and i think that discussions 
are not over about this question :)

AFAIK, in Scilab 6, a null object can only be an undefined component of 
a list:
L = list("abc", , %z);
type(L(2))
x = L(2) // should do the same than x = clear("x") (that actually looks 
like a hack :/)

Hello Samuel,

Thank you for your answers.

- *Building toolboxes*: I did not know that tbx_make() was functional, 
it seems the way to go in the future indeed. At the moment, it seems to 
be a bit unstable though and produced a segfault in my case,

terminate called after throwing an instance of 
'GiwsException::JniCallMethodException'
   what():  Exception when calling Java method :
Segmentation fault (core dumped)

- *Using 'error()' in overloading functions*: I'm not sure to understand 
what you mean?

To overload the extraction for both 1 and multiple indexes (as 
matrices), e.g. a(1), a(1,2), I used,

    function out = %myType_e(varargin)

    // the object is always varargin($),

    // the indexes are varargin(1:$-1)

    endfunction

to cover all the cases in one function. This actually works, but using 
error(' ') within this function does no longer display the error 
message, instead, it says that the overloading is not defined.

- *Performances for solving A*x = b*: On Scilab 5, the code

    n = 100; A = rand(n,n);b = rand(n,1);x = A\b;

leads to a segfault for n >= 18 (maybe a problem with the package in 
ubuntu?). Hence I did not really test the performances.


- *Equivalent to x = clear('x') in Scilab 6*: I see., I 'll stick with 
empty variables for the moment.


Best regards,

Pierre

PS: I understand. I just did not want to spam the list with multiple 
questions.

Hello Vic,

For compilation of Scilab, we provide Visual Studio 2013 solution.
For compilation of toolbox/code, you can use VS2010, VS2012, VS2013 and 
VS2015.

Scilab 6 on Windows provides Visual C++ redistributable 2013.
So for better compatibility/portability, I suggest you use VS2013 ( Pro 
or Express[1] )

Hope that helps,
Antoine

Hello all.

Month after month we expected to hear the release of the 6th version. But
now, we had gone from no news to good news.
We all know it wasn't as easy as it looked. So my warmest thanks to all the
folks who engaged to make Scilab fresher and stronger.
I wanna take my hat off to them all right here. :-) 

I was wondering what happened to the object-oriented programming paradigm
which has been promised for Scilab 6?
Will our wish really be fulfilled?

Merci
Mehran

	6.0
Message-ID: <CADK7Jf=7VawEPpm-_0C6PzgiVtkMHtfh6JE==R9NU3U5nN_=3g@mail.gmail.com>

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

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?

Dear Scilab team,
thank you very much for the new version!

But when I try to start "Scilab 6.0.0" from the Windows 7 Start menu I 
get this message:

"Scilab cannot create Scilab Java Main-Class (we have not been able to 
find the main Scilab class. Check if the Scilab and third-party

Only "Java 8 Update 121" is installed.

"Scilab Console" or "Run as Administrator" with "Scilab 6.0.0" does work.

Hi Cl?ment,
Thank you for your mail. I downloaded the Command Line Tool as suggested by Paul in my Mac. It works! I found out that "gcc" and "g++" are symlinks and they are not "real" compiler because there is no entry for "man gcc" in Mac OSX. The real name is Clang and Clang++... Please correct me if I told something wrong about this issue. However, I suppose that the Clang and Clang++ work like gcc and g++ in Linux, respectively, don't they?
So, I gave up to use Eclipse IDE for C++ because I cannot adapt myself to the project-based philosophy. Therefore, I would like to program using another software, perhaps, Gedit or something else like that for Mac OSX.?
What do you suggest, please? And how could I install it in the Mac OSX Sierra?
Thank you very much.
All the best,Reinaldo.
PS: Is this Xcode Command Line Tool enough to run Scilab 6.0? Thanks.

 Hi Reinaldo and welcome,

Yes Paul is right and just for completness (and CC-ing dev) :

We ?currently do not require an IDE to build Scilab ; you can program using vim / emacs / notepad++,
gcc / clang / msbuild. As common IDEs provide a way to import an exiting code base as a new project,
we also do not provide project files (other than the VisualStudio ones required by msbuild).

PS: I personally use Netbeans and/or Eclipse JDT for Java programming. Eclipse CDT and/or Vim (with
YouCompleteMe) for C/C++ programming.

I was looking at left tree, expecting the Font option under the

Hi Stefan,

Could you open a bug with all your system information please ?

As you might known, we not only build scilab but also pass the tests on the binary version using a
set of different machines before releasing. This is likely a bug in your local configuration (either
graphical card or software setup); please describe what's specific in your setup and post the result
of `[s,d]=getdebuginfo()` using Scilab 5.5.2.

Thanks,

Thanks for clarifying things :), indeed it was not easy to replicate behaviors implemented 20 (and
more) years ago ! Hopefully the interpreter code is much more understandable right now and newcomers
can get into it in less than a week (as GSoC students does) !

> I was wondering what happened to the object-oriented programming paradigm

Well, the 6.0 family target a Scilab 5 compatibility without "visible" language improvements ; the
object-oriented paradigm hasn't been added yet and we still need more concrete advantages for the
Scilab language to define it !

Especially, function visibility (in modules and function scopes) is IMHO more needed than class
definition. We wrapped successfully Java objects without syntax addition and any user can add
javascript or python object-like implementation where `this` would be an `mlist("myclass" ...)`
value [1]. If you have some specific need on it, do not hesitate to describe it on dev at lists.scilab.
org and we can start/iterate on the implementation.

Thanks,

Hello !

I had the same problem.
The work-around is to copy the ?scripts? directory (in MinGW home directory) in ?macros?.
I already opened a ticket about this point.

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

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\atoms\x64\mingw\010~1.0\macros\scripts\TEMPLATE_MAKEFILE.MINGWnot found.

Also I tried to launch Xcos model with Modelica blocks with xcos("SCI/modules/xcos/demos/Electrical/Bridge_Rectifier.zcos");
then with Simulation->Start got error in console

 c_pass1: build the modelica meta-block failed

 xcos_simulate: Error during block parameters update.


After manual move of 'scripts/TEMPLATE_MAKEFILE.MINGW' to 'macros/scripts/TEMPLATE_MAKEFILE.MINGW' atomsTest('mingw')
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 on a Platform and Chaos Modelica)

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?

Hallo Community,

I need in my model a Variable Capacitor. But in Xcos-Paletten-Browser there
is not one. There is only a variable resistor block.

How can I manually create a variable capacitor block for my simulations in
Xcos ?

Thank you in advance!

Hello Theodoros

In Scilab 5, you shall install the Coselica module!
|--> atomsInstall("coselica")
|Then
--> help
you will find the /MEAB_VariableCapacitor / in the Electrical palette

/Coselica/ is not yet available in Scilab 6
IMO, it shall be the top1 priority of External Xcos modules to port it 
to Scilab 6.

Samuel

Subject: [Scilab-users] How to use Genetic Algorithms to optimize a function
 with multiple parameters?
Message-ID: <1487590305242-4035535.post@n3.nabble.com>

Dear Scilab community,

I am completely new to Scilab. Since I would like to get used to Genetic
Algorithms, I experimented a bit using the documentation's examples. Until
now, I am quite happy. My first steps went well, but I have got a question
regarding functions with multiple input parameters:

I experimented with optim_ga examples I could find in the documentation. All
of these examples had only one varying parameter, i.e. f(x). Now, I would
like optim_ga to find the minimum of e.g. Rosenbrock function or Ackley's
function, i.e. f(x,y). What do I have to do to find the minimum of such a
function with two (or more) parameters with optim_ga?

Even though I know that the following code does not work since it passes
only one parameter to function 'rosenbockC', it demonstrates my approach
(and surely why I fail, too).

clear;
clc;

// Rosenbock
function f=rosenbrockC(x1, x2)
    x = [x1 x2];
    f = 100.0 *(x(2)-x(1)^2)^2 + (1-x(1))^2;
endfunction

// Optimization parameters
PopSize     = 100;
Proba_cross = 0.7;
Proba_mut   = 0.1;
NbGen       = 10;
NbCouples   = 110;
Log         = %T;

ga_params = init_param();

// Parameters to control the initial population.
ga_params = add_param(ga_params,"dimension",2);

// Optimize
[pop_opt, fobj_pop_opt] = optim_ga(rosenbrockC, PopSize, NbGen, Proba_mut,
Proba_cross, Log, ga_params);

Thank you in advance for your help.
Hans

Just a thought... I don't know about the model component you are using 
but if you change the value of a capacitor while it is charged the 
voltage changes. So choosing the value for a component in a circuit is 
one thing. Dealing with a charged capacitor which changes can produce 
some interesting effects. Conservation of charge and energy balance must 
be considered.

Subject: [Scilab-users] How to use Genetic Algorithms to optimize a

Hello,

I think I found something that helps: Datasheet 'Optimization in Scilab'
contains an example on pages 5/6 that uses Rastrigin function with
parameters x1 and x2. In the example, these parameters are binarily encoded
first. I just copy/pasted the example and it works. Now I'll try to use this
as a starting point.

Kind Regards,
Hans

Yep they are also supported as compilers in our ./configure script and Makefiles.

I have no experiences on a specific editor for MacOS X, maybe Xcode (without the IDE features) or
simpler things like Atom. Vim has a better taste for me (cross-platform) with its quick Cut Paste
Sed features and LLVM based code-completion (provided by YouCompleteMe).

> PS: Is this Xcode Command Line Tool enough to run Scilab 6.0? Thanks.
I have no experience with it, but probably yes :). MacOS X is a platform we target but we do not
have developers working on it from day to day.

It depends on what you're simulating -- if it's an RLC circuit and the
cap value is changing slowly with respect to the resonant frequency,
for example, then that's not so big a deal. ?Ditto if you're using a
variable cap block to model a Varicap diode (which isn't going to act
like a mechanical capacitor whose plates are moving in and out).

But yes, if you're modeling a real live phenomenon with conductors
moving in relation to each other, and if it's in a broadband circuit,
then you at least need to worry about conservation of charge.

Hello,
I got Scilab 6 to work in a Windows 10 laptop. However, my loading of 
data with read() took almost half an hour.
 From toc() and mprintf():
Loading of data took 26 min 23 sec

In Scilab 5.5.2 it took just over a second.
 From toc() and mprintf():
Loading of data took 1.219 sec.

What happened?

Stefan

Hi all,

Just a general query, but has anyone noticed that it takes a lot
longer to load Scilab 6 on Windows compared to v5.5.2 (64-bit)?

Only installed a little while ago, but 5.5.2 loads really promptly on
a laptop with 4 Gb of RAM and a selection of modules starting, whereas
version 6 takes a while to get going (with no modules).

Cheers

Lester

Haven't got as far as testing the functions, but just starting version
6 compared to 5.5.2 is slower; not sure what is going on. Testing on
Windows 8.1 (4 Gb RAM).

Do you have a test script to try, see if the issue can be reproduced?

Cheers

Here you are, Lester! A script that generates a comparatively small 
data file and then reads it is attached.

In a small laptop computer with Windows 10 and 32-bit versions of Scilab:

Scilab-5.5.2:

size(mat) = [10000  7]
mat took 0.08 sec to read.
size(mat) = [10000  7]

Scilab-6.0.0:

size(mat) = [10000  7]
mat took 39.14 sec to read.
size(mat) = [10000  7]

Stefan

Hi Stefan, Lester,

I confirmed the issue (0.02s in 5.5.2 vs 6.90 in 6.0.0) and on a local build I am able to trace the
issue using the Linux perf tool:

+???58,69%????58,68%??libsciast.so.6.0.0??????????????[.] types::getIndexesWithDims??????????????
+???22,09%????22,08%??libsciast.so.6.0.0??????????????[.] types::ArrayOf<double>::resize?????????
+???12,18%????12,18%??libsciast.so.6.0.0??????????????[.] types::getIndexWithDims????????????????
+????4,04%?????4,04%??libsciast.so.6.0.0??????????????[.] types::ArrayOf<double>::getIndexes?    

So it seems that too much resizing occurs :/ . Could you post a bug with your test case please ? 

Thanks,

Thanks Stefan for the script:

Windows 8.1 (64-bit) 4 Gb RAM

Program load time (approx)
5.5.2 ~9 seconds (with modules installed)
6.0.0 ~20 seconds (no modules)

5.5.2 results:
size(mat) = [10000  7]
mat took 0.04 sec to read.
size(mat) = [10000  7]

6.0.0 results:
size(mat) = [10000  7]
mat took 13.62 sec to read.
size(mat) = [10000  7

Cheers
Lester

Subject: [Scilab-users] Scilab 6.0 C++ API // Crashes due to function calls
 via overloading mechanism
Message-ID: <20170223105740.4387246a@lemon>

Hello,

Using the precompiled "scilab-branch-6.0-1487071837" under Linux 64bit,
I am experiencing crashes "Segmentation fault (core dumped)".

I am trying to use the new C++ API to implement operations like
addition for an user-defined type, lets say "T". 

To reproduce the crashes, I have stripped everything down to the
following minimal example:

1. Implementation of addition operation for Type "T" using C++ API:
-------------------------------------------------------------------

types::Function::ReturnValue sci_T_a_T(types::typed_list &in, int
_iRetCount, types::typed_list &out) { try
	{
		return types::Function::OK_NoResult;
	}
	catch(std::exception& e)
	{
		return types::Function::Error;
	}
	return types::Function::OK_NoResult;
}

2. Compile "sci_T_a_T" and map it to "%T_a_T" Scilab function
-------------------------------------------------------------

3. Use "%T_a_T" directly => OK
------------------------------

A=tlist("T");
B=tlist("T");
%T_a_T(A,B) // OK

4. Use "%T_a_T" via overloading mechanism of "+" operator => Crash
------------------------------------------------------------------

A=tlist("T");
B=tlist("T");
A+B // => Crashes Scilab (Segmentation fault (core dumped))

------------------------------------------------------------------

So, it seems that using "try-catch" is a problem, when the function is
called via Scilab's overloading mechanism!?

What am I doing wrong, or is it a bug of Scilab?

Please note, that avoiding "try-catch" is not really an option for me,
because I have to use C++ functions from a library with error reporting
via exceptions.

Thanks for any advice and further insight,

Dirk

Hello Cl?ment,
I will first tell you some odd things. It appeared that Scilab 5.5.2 
had got exactly the same issue in this computer (I had not used it for 
a while)! I know that the only changes since I last used it were, 
besides installation of Scilab 6, updates of Java and Windows 7 Pro.

I uninstalled Scilab 6, then uninstalled and reinstalled Scilab 5 to 
no avail.

As far as I can imagine, it must be a permissions issue that is not 
present in the Console?

Do you have a hint? Do you still want me to open a bug?

Best regards
Stefan

These kind of issues are always hard to fix, usually I recommend to install Scilab in an up-to-date
computer. Could you try launching scilab from the command-line and log any issue ?

Note: opening a bug will log the issue. This is useful to track the number of impacted users as well
as keeping track of related information. I always prefer closing a bug as "WONTFIX" or "INVALID"
rather than looking for information on a ML thread :).

Thanks,

What do you mean by "X, Y position of the coordinate values of the 
matrices"?
Could you provide an example with a simple input and the required display?

You may have a look at the *vec2list*() macro, and *pack*() and 
*unpack*()  (may be with some adaptations).

I agree: functions processing containers or data in heterogeneous 
containers are missing or too poor.

Indeed, this would be a very handy and straightforward way to run a 
parallelized loop.

For the time being, although  its help page is still distributed,
https://help.scilab.org/docs/6.0.0/en_US/parallel_run.html
*/parallel_run/* has been removed from Scilab 6
--> parallel_run
Undefined variable: parallel_run

It was pointed to one year ago: http://bugzilla.scilab.org/14486

And some MPI features announced in the restricted 6.0.0 release notes 
are not actually distributed:
/* MPI_Create_comm create a new communicator from MPI_COMM_WORLD using 
MPI world ranks.//
/
--> MPI_Create_comm
Impossible to load mpi.dll library

at least on the MSWindows 64 bits plateform, for which the Scilab 
installer proposes by default to instal the MPI module.

So, parallelization is somewhat regressing. On windows, not really, 
since parallel_run never actually addressed more than one processor.

Subject: [Scilab-users] Strange behaviour of the auto-indent ctrl + i
Message-ID: <bf6bca3f47c6136b31038b02c933fdf5@pierre-vuillemin.fr>

Hello all,

I've just realised that block-comments are now available in Scilab 6 and 
I find it quite convenient. I've noticed strange behaviour when using 
the auto-indent tool ctrl + i in scinote though.

For instance with this code



// Author : Pierre Vuillemin (2017)
// License : GNU GPL

function problem = sopi_max(fun, varargin)
    /*
    Creates a maximisation problem.

    Calling Sequence
       problem = sopi_max(fun)
       problem = sopi_max(fun, c1, ..., cn)

    Parameters
       fun      : the objective function (sopiVar)
       ci       : constraints (sopiCst or list of sopiCst)
       problem  : the optimisation problem (sopiPro)

    See also
       sopi_var
       sopi_min
       sopi_solve
       sopi_example
    */
    problem = sopi_min(-fun, varargin(:))
endfunction


the auto-ident tool adds strange indentation to the endfunction + it 
suppress the indentation of the text withing the block comment. 
Shouldn't it behave as if // were used?

Regards,

Pierre

Hi Pierre,

The handling of comments looks buggy indeed, could you please report a 
bug <http://bugzilla.scilab.org/enter_bug.cgi?product=Scilab%20software> 
with the test-case?
Thanks!

Regards,
Paul

Hello Nils,

I filed a bug for your report, we're looking into it, turns out the 
labels don't work for simple blocks either!

Thanks your your feedback,

Subject: [Scilab-users] Curing scf() & figure() slowliness: a good target
	for Scilab 6.0.1
Message-ID: <0b84b337-7106-a05e-66db-c728778cc762@free.fr>

Hello,

Opening a new empty figure (without drawing anything) is a so common 
elementary task and it has become so long that i have built a short 
benchmark about it from Scilab 4.1.2 to Scilab 6.0.
Detailed results are here-below. The main conclusions are the following:

 1. with no pre-existing figure,*scf**() is **20 times slower in **5.5
    and 6.0 than in *its best performances in *5.3.0*. On my computer,
    it takes 0.062 s with 5.3.0 and 1.3 s now (5.5.2|6.0).
    Scilab 5.4.0, 5.4.1 and 5.5.0 have dramatically damaged performances.
    The loss is even 10x bigger with figure(): it is ~200 times slower
    with Scilab 5.5 & 6.0 than with Scilab 4.1.2

 2. Since Scilab 5.5.0, the time taken to open a new figure increases
    linearly with the number of already opened figures. On my computer,
    opening the first one (after loading scf()) takes 1.8 s, and opening
    the 20th one takes almost 10 s. This is still the case with Scilab 6.0.

*Detailled results: *

 1. Opening the first figure :
    Only 2 tests are reported with figure() instead of scf().

    ?t=0;  for  i=1:50,  tic();  scf();  t=t+toc();  xdel();  end;  t,  t/50
                      [s]              [s]      4.1.2 base  figure()
    6.0.0  :  62.39/50   1.248    18.5 2.32
    5.5.2  :  73.62/50   1.4723   21.8
    5.5.0  :  69.94/50   1.3988   20.8
    5.4.1  :  37.33/50   0.7466   11.1
    5.4.0  :  24.07/50   0.4814   7.14
    5.3.0  :  3.102/50   0.0620   0.92
    5.1.0  :  4.069/50   0.0814   1.21
    4.1.2  :  3.370/50   0.0674   1.00 0.014

 2. Opening 20 figures :

    t=[];  for  i=1:20,  tic();  scf();  t(i)=toc();  end;  sum(t)/20

    6.0.0  :  5.30  [1.35  =>  9.51]
    5.5.2  :  5.68  [1.77  =>  9.92]
    5.5.0  :  5.66  [1.82  =>  9.85]  range from the #1 to #20
    5.4.1  :  1.18
    5.4.0  :  0.923
    5.3.0  :  0.110
    5.1.0  :  
    4.1.2  :  0.0774

Subject: [Scilab-users] Bode of discret time transfer function.
Message-ID: <SN1PR10MB0383BAE6ABD85478C3EC0350EE550@SN1PR10MB0383.namprd10.prod.outlook.com>

Hi:

This is the first time i work with discrete time transfers functions and Scilab.

I want to use bode() for plotting the magnitud and phase response of the system, however, i don't understand how to set the frequencies to normalized values (-pi, pi).

This is what i'm doing:


s=poly(0,'s')
H=(s^(-2400))/(1-0.5*s^(-2400))
S=syslin('d',H)
bode(S)


i get a warning that frequencies beyond nyquist rate are ignored and the resulting plot is attached.

[cid:4845973f-0da4-4dd3-ade0-64a7e55422d3]

In the help, it says that bode parameter could include fmin and fmax in herz, but isn't a discrete system response limited to normalized frequencies? And to transform the normalized frecuency to herz the sample rate must be used, but i don't know how to pass it to the system or something.


Any hints would be appreciated.

Thanks

S=syslin(dt,H) defines a dynamical system sampled. dt beeing the

If you want the frequency uniis be in rd/s add "rad" as last input argument

First, 'bode' is going to give you a Bode plot, and it's going to be
insistent on giving it to you in log-log format -- so if you want a
plot on a linear frequency axis from -pi to +pi, then you need to do it
by hand.
Second, 'bode' is pretty insistent about reporting things as per second
-- if you define a system as 'd' then it'll act like the system is
sampled at 1Hz.
If, for instance, you run:
H = syslin('d', (%z - 0.9) / (%z - 1));
g = scf(0); clf; bode(H, 0.001, 0.4999, 'rad')
You will get the following plot:
It puts the vertical red lines there, presumably to mark Nyquist, even
though we're displaying in radians per sample, and it reports things as
radians/s. ?You can get into the guts of the graph and fix it up,
though:
delete(g.children(2).children(1)); ? // Delete the top red line
delete(g.children(1).children(1)); ? // Delete the bottom red line
g.children(2).x_label.text = "Frequency (rad/sample)"; ?// Change the
top text
g.children(1).x_label.text = "Frequency (rad/sample)"; ?// change the
bottom text
Do all this, and you get:

Not sure what you're trying to achieve, but if you want a plot of the
linear amplitude response on a linear frequency line, use Horner:

H = syslin('d', (%z - 0.9) / (%z - 99));
th = %pi * (-1:0.01:1)';
clf; plot2d(th, abs(horner(H, exp(%i * th)))); xgrid(2)

Is there a function of Bessel cubic spline?
I mean Besse cubic spline as follows.
1,pieacewise 3 degree polynomial on the each interval [x(i),x(i+1)] for
i=1,2,..,n-1
2,f(x(i))=y(i) for 1=1,2,..,n
3,continuous at all xi for i=2,...,n-1
4,differnciable at all xi for i=2,...,n-1
5,f''(xi) for i=2,...,n-1 is same as the slope of a quadratic function which
pass 3 points (x(i-1),y(i-1)) (x(i),y(i)),(x(i+1),y(i+1))
5,f''(x(1))is same as the slope of a quadratic function which pass 3 points
(x(1),y(1)) (x(2),y(2)),(x(3),y(3))
5,f''(x(n))is same as the slope of a quadratic function which pass 3 points
(x(n-2),y(n-2)) (x(n-1),y(n-1)),(x(n),y(n))

     Hello,

    this is the option "fast" of the splin function (use splin to compute
   the spline and interp to evaluate it at some points).

Have you looked at the help for the 'splin' function, to see if any of 
the various flavors of spline that it will compute is what you want?

Subject: [Scilab-users] A working scilab 6.0 icon in KDE
Message-ID: <CAOsmt4Vv7d55dO7QtK7PC26e4d9LgdUWmCuyoGv5G+h3sdd3pw@mail.gmail.com>

Has anyone succeeded in creating a "link to application" in desktop area to
launch scilab 6.0 in KDE 5 plasma?

Here, a desktop scilab 6.0 icon does launch scilab 6.0 but it crashes
immediately.

I can launch scilab 6.0 from command line without any problem.

An equivalent desktop icon to launch scilab 5 works properly.

Thanks

Dear Adelson Oliveira!

There is a bug with Scilab 6 launch from .desktop shortcut - see bugzilla
#14682 <http://bugzilla.scilab.org/show_bug.cgi?id=14682>.

As temporary solution I created launcher with command:

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

I tested it in MATE, GNOME and Unity.

Hope this helps.

Dear Nikolay Strelkov,

I tested in KDE 5 plasma and it works fine as well.
BTW, I used only,

xterm -e /scilabdirectory/scilab

no change or reference to the LC_ALL environment.

Thanks a lot

Message-ID: <CAOsmt4U4MpEEy8ej==ubyDFTA9sJn+aqfWudJYGtJ-AyH7njuQ@mail.gmail.com>

Hi,

Let's take fft as an example.

In scilab 5 one could call fft specifying parameters like dim and incr by
name,

fft(A,-1,dim=100,incr=1)

Codes that used to work in scilab 5 now gives wrong results (no error
messages!) in scilab 6 because the new release ignores named parameters. To
get expected results with scilab 6, one should recast the command above as,

fft(A,-1,100,1)

otherwise scilab 6 reads

fft(A,-1)

instead!

What for ignoring parameter names? Also, I have some scilab codes where
functions do accept names and take different actions accordingly. Should I
change all these codes to use scilab 6?

Thanks

Is this true? ?Parameter passing by name is hugely useful -- they'd
have to re-write a whole bunch of libraries to make it work, and I'd
have a lot of stuff that would be instantly obsolete.

Hello Adelson,

Here names are simply ignored. There would be a true call by names if 
the order would not matter, while it does:
-->Fp2 = fft(A,-1,incr=1,dim=100);
                                !--error 999
fftw: Wrong values for input argument #3: Elements must be greater than 1.

I guess that this is because fft() is a built-in, not a "macro".
But even for functions written in Scilab language (aka macros), passing 
named parameters is strongly discouraged:

  * this sets a formal link between the calling level and the inner
    called one. Then, any change of the parameters names in the function
    definition breaks such calls.
  * the definition of most (say 99%) scilab functions test input
    parameters against their position rather than their name. It is not
    robust, but so it is. So (provided that fft() would be a macro) when
    calling fft(1,-1,incr=1), incr is detected at the third position
    while in the definition it is listed in the 4th one. Really
    efficient to get a mess ;)

    function  test(a, b)
         mprintf("RHS=%d, exists(a)=%d exists(b)=%d\n",  argn(2),  exists("a","l"),  exists("b","l"))
    endfunction

    -->test(b=1)RHS=1, exists(a)=0 exists(b)=1-->test(b=1,a=2)RHS=2,
    exists(a)=1 exists(b)=1

So, Tim is right. Calls with named parameters make the code fragile, or 
make somewhat harder to code the analysis of input arguments in a robust 
way. This coding way still increases functions overheads, that make them 
slower.

You misread my comments. ?Tim _likes_ named parameters. ?If Tim were on
the C++ standards committee (which is as likely as pigs flying, BTW)
Tim would agitate that named parameters be adopted into that language.
?Scilab, Verilog, and (I think) VHDL have it, and particularly in a
language that allows for optional parameters, I feel that when you have
to have function calls with more than a few parameters it vastly aids
code readability.

Hmmm, actually, i don't really think so. It would be more robust but 
also more straightforward and readable to test the existence of input 
parameters according to their name instead of according to their number 
and position.
But this is not the way used in most functions definitions.

Sorry for my misinterpretation.
I agree that it is easier to use named parameters rather than to have to 
count and feed many "empty" or default positions to reach useful 
trailing ones. But when a parameter has been badly named when designing 
the function (*), then it is done and over. We must bear it all the 
time. And this is not nice at all.
Same thing when you want to add a parameter that has a meaning close to 
another already existing one. Then keeping things (names) clear may 
become hard. Moreover, things get more complicated when using varargin 
(that ignores names).

(*) this is often the case. Scilab misses a standards committee, also to 
well name things.

Well, now scilab 6.0 ignores named parameters at fft calls. One can check
it with

fft(eye(4,4),-1,dims=4,incr=1)-fft(eye(4,4),-1)

the result is 4X4 matrix with zeros. This is different from (without names):

fft(eye(4,4),-1,4,1)-fft(eye(4,4),-1).

Then, I guess it is to say optional parameters are no longer "fully"
optional, they must be provided in their order ...

But anyway, it seems that my personal "macros" or functions still work with
named optional parameters (opt1, opt2, ....) treated as,

   if exists('opt1','local') == 0 then
      opt1 = default_opt1.;
   end

BTW,

Scilab has always had problems to provide interfaces to languages that
accept optional parameters (but not only because of it) like modern FORTRAN.

Adelson,

It could somewhat misleading to get conclusions about Scilab behavior  
with named parameters out of the current fft() behavior, because there 
are some pending bugs about fft(), independently from named arguments. 
IMHO, it would be safer to do tests about named arguments with another 
builtin but healthy function.

Yes, for macros things are "simpler". There is just that isdef() (or 
exists()) applied to a skipped input parameter (like in myfunc(a, ,c)) 
returns %T (or 1) although the parameter is not defined.

Yet even knowing all of that, and agreeing with most of it I would still 
vote for named parameters.  Even with the difficulties around varargin.

Please try the following:
edit("SCI/modules/atoms/macros/atoms_internals/atomsDESCRIPTIONget.sci",194)
// It is the line #178 in local numbering
//replace the line #178
extract_cmd = """" + gzip_path + """" + " -d """ + file_out + """";
//with
extract_cmd = """" + gzip_path + """" + " *-f *-d """ + file_out + """";

//Save the file. Then do:
cd SCI/modules/atoms/macros/atoms_internals/
predef clear                     // unprotect libraries to be able to 
recompile atomsinternalslib
genlib atomsinternalslib // recompile the sub-library to take the change 
into account

//Then, try to rerun the ATOMS Gui..

Hello!
I have experience to write software and know about more dimensional arrays.

If a look in Variable Browser and than use the function size()
I'm wondering, that "r" means the vertical numbers.

Have you a tip for a very basic letter which explains this?

Thank you
