Hi Jaundre Venter

your code runs just fine

you just ploted y(9) and y(8) instead of y(9,:) and y(8,:) !

it happens that when M is a matrix, say a 3x4 matrix, things like M($), 
M(1), M(7) or M([1 3 5 9]) are legal scilab statements, so you don't 
have any error message.
see the documentation: help extraction

*scilab team*, maybe you could put an option for displaying warnings 
when tables are accessed with less arguments than their dimensions, what 
do you think?

Subject: Problem with scilab 5.3.3 and graphics
Message-ID: <4EB1116E.9060004@free.fr>

Hello,

I am under mandriva 2011 + I have updated my nvidia driver to the latest 
version.
When I launch a graphic, nothing is displayed and a strange error 
message is printed in the bash console:

Maximum number of clients reachedMaximum number of clients 
reachedMaximum number of clients reachedAn error occurred when Scilab 
tried to open a Canvas: Unable to open default display, needed for 
visual selection and offscreen surface handling
If an exception about java.lang.UnsatisfiedLinkError has been thrown, 
check if etc/librarypath.xml contains the path to gluegen and jogl libraries

I use the scilab shipped by mandriva. I've got the same behavior with 
scilab-5.3.3 64 bits downloaded from the website.

Best regards,

YC

Argghh !

It's a problem related to Xorg / KDE / Gnome.
With some versions of KDE, many ports are opened. And Xorg can only 
manage a maximum amount of opened ports (256).
I switched to XFCE for now until a patched version of KDE is released.

Some similar problems have been reported with firefox and thunderbirds 
(with some specific plugins).

I use Mandriva 2011 64 bits updated as to yesterday and Scilab 5.3.3 64 
bits downloaded from the website. So far, I have not had this problem.

Subject: [ANN] Scipad-8.68
Message-ID: <4EB1A5AD.5060201@free.fr>

ANNOUNCE: Scipad version 8.68
=============================

A new version of the Scipad text editor for Scilab and Scicoslab is 
available.

This is a bug fix release.


CHANGES SINCE PREVIOUS VERSION
==============================

FIXED BUGS:

  * Fixed ticket #13 (emacs bindings mixed with mac-pc bindings)

  * Fixed bugs with incremental search:
     . F3, find a match, insert a line before the match, F3 --> wrong
       highlighting
     . The searched string could keep the red color even if there was
       a match

  * Fixed: only Scilab scheme colorized buffers shall be executed on
    Load all into Scilab

  * Fixed: new Scipad version check failed due to a change in the
    content of the queried SourceForge page


WHAT IS SCIPAD ?
================

Scipad is a powerful editor and graphical debugger for programs 
written in Scilab language. It is a mature and highly configurable 
programmer's editor, including features like syntax colorization, 
regexp search/replace, parentheses matching, logical/physical line 
numbering, peer windows, line and block text editing, and much more. 
Scipad can be used along with Scicoslab or Scilab, but even as a 
standalone text editor. Used as internal Sci(cos)lab editor, it 
interacts tightly with the interpreter, allowing

  - Scilab code execution control
  - conditional breakpointing
  - variable retrieval and tooltip display
  - Scilab help lookup
  - access to source code of Scilab library function
  - control of Scilab facilities for Matlab code and creation of
    help documents
  - and much more

Scipad also includes basic Modelica and XML syntax colorization; it is 
currently localized in 13 languages and further localizations can 
easily be added. Scipad is entirely written in Tcl/Tk and Scilab 
language. It has been tested and developed under various versions of 
Windows and Linux.


WHERE CAN SCIPAD BE FOUND?
==========================

Project page @ SourceForge.net: http://sourceforge.net/p/scipad/

Readers,

The tarball was downloaded and expanded.

Java is installed at:

/usr/local/java/java/

The bash profile file contains:

export JAVA_HOME=/usr/local/java/java/jre/bin/java
PATH=$PATH:/usr/local/java/java/jre/bin:/usr/local/bin
export PATH

The libjava file is at:

/usr/local/java/java/jre/lib/i386/libjava.so

The scilab file was edited:

detect_java_vm() {

    proc="i386"

    # If the user has the variable JAVA_HOME in the ENV

    if test -n "$JAVA_HOME" ; then

        if test $SCIVERBOSE -ne 0; then
            echo "Using specified vm: $JAVA_HOME"
        fi

#        if test ! -x "$JAVA_HOME/bin/java" ; then
        if test ! -x "$JAVA_HOME" ; then
            echo "Cannot find $JAVA_HOME/bin/java"
            exit 1
        else
            JAVA_BINDIR=$JAVA_HOME/bin
        fi

        # Manage JRE & JDK because libjava.so and others are stored in the JRE
        if test -d $JAVA_HOME/jre; then
            JRE_HOME=$JAVA_HOME/jre
        else
            JRE_HOME=$JAVA_HOME
        fi

        # Configuring LD_LIBRARY_PATH for libjava.so libhpi.so and libxxxx.so

        JAVA_SHLIB="libjava.so"
#        LIBJAVA="$JRE_HOME/lib/$proc/$JAVA_SHLIB"
        LIBJAVA="$JRE_HOME/../../lib/i386/$proc/$JAVA_SHLIB"

Trying to start scilab causes an error:

/usr/local/scilab/scilab/bin/scilab

Could not load JVM dynamic library (libjava).
Error: libjvm.so: cannot open shared object file: No such file or directory
If you are using a binary version of Scilab, please report a bug
http://bugzilla.scilab.org/.
If you are using a self-built version of Scilab, update the script
bin/scilab to provide the path to the JVM.
The problem might be related to SELinux. Try to deactivate it.

Scilab cannot open JVM library.

Any help please?

This declaration is wrong. 
JAVA_HOME must point to a path which should be
/usr/local/java/java 
here

JAVA_HOME=/usr/local/java/java scilab 
should start Scilab

FYI, 
SCIVERBOSE=1 scilab 
will give you some debug information.

It should not.

Anyway, first, why are you not using Scilab official binaries ?

Please use the exact command as I told you:
JAVA_HOME=/usr/local/java/java /usr/local/scilab/scilab/bin/scilab

I assure you it does, for examples using jedit, freeplane, rssowl.

Because it wants to install extra java software and I have already
java installed.

That does not work:

JAVA_HOME=/usr/local/java/java /usr/local/scilab/scilab/bin/scilab

Could not load JVM dynamic library (libjava).
Error: libjvm.so: cannot open shared object file: No such file or directory
If you are using a binary version of Scilab, please report a bug
http://bugzilla.scilab.org/.
If you are using a self-built version of Scilab, update the script
bin/scilab to provide the path to the JVM.
The problem might be related to SELinux. Try to deactivate it.

Scilab cannot open JVM library.

When I switched to XFCE, I noticed that a process eat all the ressources of on processor. This process is knotify4.
I think this is the source of my problem. I will try again under kde4 but I will kill knotify4 before launching scilab.

Hi!

I've been looking for a way to integrate my correlation analysis in scilab,
which needs spearmans rho.

Is there a ready-to-use package to install somewhere?

Otherwise I found this:
http://books.google.com/books?id=K4kMx3EWj9MC&pg=PA68&lpg=PA68&dq=spearman+scilab&source=bl&ots=KrBZp9IKya&sig=pCm0jcrnybCcwEfpMmzjmdJ_KNY&hl=en&ei=e-uyTrH3BNLQ4QTGxKTwAw&sa=X&oi=book_result&ct=result&resnum=5&ved=0CDkQ6AEwBA#v=onepage&q=spearman%20scilab&f=false

How do I implement this into scilab on my own so it becomes a useable
function? (if none exists already that is..)

If scilab 5 requires java, why is it not compiled as a jar file? It is
too difficult to configure. Programmers should consider that other
java software would be installed before scilab.

Here, the problem is because you haven't installed java hdf5.

I don't understand your point.

I am trying once more my question, why are you not using the official
binary ?
http://www.scilab.org/products/scilab/download
it is providing an out-of-box fully functional Scilab.

If you are are using the packaged version of Scilab by Opensuse and you
are experiencing these issue, please report them on the opensuse bug
tracker. The maintainer is usually reactive.

Usually, other java programs are very easy to install. For unknown
reason, the official build demands that a separate version of java is
installed, even if the computer already has java. Why?

See above. As an example, installing jedit allows the user to edit the
executable file to use an existing installation of java. Scilab
installation does not allow this.

To repeat, using the command 'urpmi', the installation process
demanded that java is installed, even though java was installed
previously to run other java programs. There does not seem to be an
option to instruct scilab to use an existing installation of java.

For scilab stock versions, we maintain a thirdparty repository with libs
supported version. With that we can assert that using a Scilab binary
version has the same dependencies for all of our supported platforms.

Exemple, I use openjdk7 with new features / new bugs / many many
changes. When I found a new java related bug, I can check if it is a
jre7 bug or a Scilab one but reproduce it with the stock version.

Well jedit has a linux installer, we do not have. Average user just need
to extract the binary tarball and execute bin/scilab. If you need more
customization then build your own Scilab.

It may be a scilab packaging issue, file a bug against opensuse
bugzilla.

Hello,

Important part :

Update hdf5 and jhdf5 versions as 1.8.2 has some major issues and we do
not support it anymore.

I do not understand; it does not explain that if the demand to install
_another_ java version before installing scilab is accepted I would
have multiple versions of java installed. This is not logical; if
every java program behaved like scilab, I would need many java
installations!

I have been using ibm java for many years, no bugs founds, stable and
works nicely with all my other java programs (except scilab).

Jedit has a java installer. Is it not possible for scilab to use a
cross-platform java installer?

To clarify this was experienced using another computer using mandriva.
So you are stating that if the installation process demands java is
installed, that if the problem with mandriva, not scilab?

Command terminal errors indicate a conflict in requirements.

rpm -i libhdf5-0-1.8.2-2.2.i586.rpm
warning: libhdf5-0-1.8.2-2.2.i586.rpm: Header V3 DSA/SHA1 Signature,

libhdf5-0-1.8.2-2.2.i586) is already installed

So version 187 was removed and installation of scilab attempted

And the original xcos error occurs! The upgrade of hdf breaks

Well, binary version *IS* binary version. We consider the JVM as
mandatory for this binary version so we provide it. Your remark also
apply to blas / lapack implementation. We ship the original
implementation, which is far less performant than more modern ones
(ATLAS, GOTOBlas, MKL) *BUT* if someone wants better performance, then
compile a specific scilab version with specific dependencies.

This is package maintainer job (distro responsibility) to provide this
version not upstream one.

We guarantee software useability on the binary version. If you install
something with a package manager, fill any bug on distro bugzilla. If
you are able to reproduce on binary version, fill a bug on scilab BZ.

Subject: Using a cell entry to access part of a matrix
Message-ID: <4EB737B5.9050407@axelspace.com>

Hi,

Could anyone tell me if, in the codes below, there is any way to make
"y(II(1))" work without error, just like "y(ii)"? I wanted to access a
part of a matrix by using an entry of a cell. I think it is a pretty
intuitive way of using a cell.

//--------------------------
y=[100:110]
ii=[1 3 5 7];
jj=[2 4 6 8];
y(ii)   // OK. This is an ordinary way.

II=cell(2,1);
II.entries(1)=ii;
II.entries(2)=jj;

II(1)
y(II(1)) // <-- ERROR

y(II.entries(1)) // OK. But not as concise as I see the benefit of using
cells.
//--------------------------



Thanks,
Iai

Thanks for your reply. I wanted to use a cell array to manage a lot of
variable in my code which is more complicated.

I guess I have to put my question in a different way:

After running the code below, type(II(1)) returns 17 while type(ii)
returns 1. According to the help, 1 means "real or complex constant
matrix". 17 means "matrix oriented typed list (mlist)". How do I convert
II(1) into a "real or complex constant matrix"?


I expected II(1) would return a matrix essentially identical as ii
because I stored ii into the first entry of a cell array, II, by letting
II.entries(1)=ii. But obviously what I expected was not the case.

hi

you could use :

m=cell2mat(II) //converts cell to matrix, what you asked.
m(1,:)



if you build yourself the cell, i am guessing you are trying to mimic
something you are used to do with matlab
in that case, consider:

1-using structures instead of cells

y=[100:110]
ii=[1 3 5 7];
jj=[2 4 6 8];
y(ii)   // OK. This is an ordinary way.

//build
II.actual_name_i=ii;
II.myindexes=jj;

//access
y(II("myindexes "))
y(II.actual_name_i )

//useful for loops
fieldnames(II)

2-using hypermatrices if ii and jj will always have the same size
II = zeros(1,4,2)
II(:,:,1) = ii;
II(:,:,2) = jj;

y(II(:,:,1))


hope this helps

Iai,

y(cell2mat(II(1)))

should be what you are looking for
(in the previous mail m was unnecessary)

Thank you, Adrien. You are exactly right. I was trying to do what I used
to do with Matlab. The code you gave me helps a lot!

Dear all,

 

I am trying to install the XCPL module and I have the following error:

exec('XCPL_Load.sce', -1);

at line       8 of exec file called by :

Do you you have any idea how to fix it please?

Hi,

 

Where can we download XCPL module ?

Yes, it's a nice exercise ;)
You may have a look at plot() or plot2d(), xarc(), xarrows(),  plot3d(),
and above all at the demos : menu ? => Demos : Menu 1 : Graphics, then
browse the examples and look at the code.

Message-ID: <4EB9B4B2.5060306@free.fr>

Hello,

The talk given by Scilab team leaders during the last ScilabTec :
Scilab 6 from a Scilab 5 user's point of view
http://www.scilab.org/content/download/2379/24494/file/ScilabTEC2011_WorkshopScilab6.pdf
is a full bunch of good news for forthcoming features & performances.
As many scilabers, i couldn't attend the talk, but reading the very 
interesting PDF brings me to
some questions.

In pages 13 & 14 : What you may wonder from Scilab 6 as a user / a 
developper,
i do not see anything about the debugger. This component is certainly among
those that the come back would be very appreciated. What about it?

About the select loop (page 21): None of the examples use grouped cases.
Is this wish abandonned?

Thank you for your attention

Samuel Gougeon

We will indeed propose a debugger in the future (we already have a
prototype).
Under which form and/or in which specific version it will be published
have not been decided.

I didn't see any comment about support of CPUs without CPU instruction 
SSE2, which was dropped in Scilab 6. Is this temporary or definitive?

Sorry to hijack the discussion, but I had a look at the pdf and could 
not understand exactly how things are evolving concerning the 
prefered/easier way to link to a c library.
For the moment, I use ilib_for_link/call but it is far from convenient.
Any change on this side?

If based on API_Scilab, the compatibility will be straightforward.

Our main objective with Scilab 6 is the compatibility, therefor, you
will find ilib_for_link/call in this version. 

However, we agree that "call" is a pain to use. It is why we are
thinking about implementing a similar thing as ctypes from the Python
world: 
http://docs.python.org/library/ctypes.html
but since the priority is on Scilab 6 itself, I cannot promise a target
release.

Message-ID: <1320853044397-3493870.post@n3.nabble.com>

I've recently installed SciLab and wanted to use it for importing data from
an ODBC server.
I've installed the toolbox Scidb but it does not seem to work at my
computer.

When I run th DbQuery demo i get the following message:
conn = struct ("provider", "QSQLITE", "database",
"C:\PROJEC~1\MatLab\SCIDB_~1.WIN\scidb_0.1\demos\addressbook")   
 
 Connecting to a database:   
 
 DbConnect(conn)   
 
 resultHandler = DbQuery("SELECT * FROM addressbook")   
Warning !!!
Scilab has found a critical error (EXCEPTION_ACCESS_VIOLATION)
with "scidb" function.
Save your data and restart Scilab.
 
 DbDisconnect()   


Anyone who has an idea what the problem is?

Hi Scilab,

Myself Saikiran, a research scholar, IIT Kanpur, India. Last week I
attended an interview. They put up a question that why you shifted to
scilab from matlab.
I simply told them that scilab is open source and matlab is closed source.
They told that is not the right answer and hence i am not selected in the
interview.
So please could u guys tell me, what are other major advantages of scilab
over matlab.

Thanks and Regards,

Well in terms of quality/price ratio, scilab beats matlab easily ;-) !

Since Scilab is open source software, one can use the source code and
modify it accordingly requirement of the project or research for personal
use or commercial use.

People can contribute toolboxes  to Scilab, that way Scilab is growing like
anything.

However, the people who do not have idea about openness of the  Open source
software may not appreciate it!

It is good to have job with Open  minded people instead!  ;-)

The transparence of how data is calculated,limitless customisation options
and the price are the main advantages of opensource imo.

Personally I'm using scilab to make a prototype of my project before we
port it to python and c-applications.

Curious to know: what was the right answer that they wanted. Perhaps
you could ask the interviewer, add the type of responses that have
published here. Maybe they will reconsider their mistake...:)

Not only is the obvious advantage of being open-source a big plus, but it also 
has the power to be improved by individual users as necessiy arises; its 
structure is completely transparent to the user.? It is also easier?to use in 
many respects--for example, you can program a function right into an immediate 
application--no need to store the?function, and call it up seperately (this also 
provides a way to 'tweak' the function to meet specific programatic needs).?

AND--updates are freely available (the open source nature can not be ignored)

TP

Hi Scilab, 

Myself Saikiran, a research scholar, IIT Kanpur, India.?Last week I attended an 
interview. They put up a question that why you shifted to scilab from matlab.
I simply told them that scilab is open source and matlab is closed source. They 
told that is not the right answer and hence i am not selected in the interview.
So please could u guys tell me, what are other major advantages of scilab over 
matlab.

Thanks and Regards,

Deat all,
it would be nice to have a function xstring3d(x,y,z,s) similar to what xstring does in 2d. It's possible to use xstring on a 3d graph, but there x and y have other meanings, so it's quite a pain.
Thank you for your attention,

WHen I woeked with project of filtering circuits one very interesting advantage I found
in scilab was in the manipulation of polynomials in theis transfer function. Look that

s=poly(0,'s')
n=s-1
d=s^2+2*s+5

h=n/d

In filtering projects, is possible to project any filter from a low pass one transforming
the variable in the polinomial. Look that

w=poly(0,'w')
s=2/w?
?now type again
n=s-1
d=s^2+2*s+5

h=n/d

Voila! The transformed transfer function

Well in terms of quality/price ratio, scilab beats matlab easily ;-) !

Hi guys,

I work on a software for distributed executions of simulation models 
(www.openmole.org). Some of our users are using scilab. In order to 
execute scilab on a computing grid we need to execute it in batch mode. 
I have tryed the option "-nw -nogui" and "-nwi" however when an error 
occurs durring the execution of the scilab script, scilab doesn't stop 
and is waiting for the user to react. Is there anyway of switching to a 
real batch mode where no interaction is ever requiered?

Cheers,
Romain Reuillon

Do you have some command line prompting for user input, like "input" ?

At the end, it displays a prompt and waits for the user to input 
something. The behaviour is similar with the -nwni option.

It works, thank you for your reactivity.

Nevertheless, I think that being able to set this beaviour from the 
command line without having to modify the script would be a great 
functionnality for distributed execution of scilab.

well, you can always try something like

/tmp/scilab-5.3.3/bin/scilab -nw -nogui -e "errcatch(-1,''stop'') ; 
exec(''Simul1.sci '')"

You could run the script inside another script, using exec. This also 
gives you control over the error level.  You could do this from the 
command line using the -e option. You can also use the -e option to call 
errcatch.

Best wishes,

Jasper.

Does Scilab have a command like mfilename in Matlab? I want to get the

Yes it does:
path = get_absolute_file_path('running_or_open_filename.m')

If you really don't know the name of the current script, you may use the
following:

[u,t,n]=file();
i = grep(n',"/(?:.*\.sci|.*\.sce)$/","r");
p = n(i(1))
// and if you need only the script name without its path nor the file
extension:
basename(p)

I would love to see an Android version and we have been contacted by a
few people for a port. However, I haven't seen anything yet.
For now, we, the Scilab consortium, are not working on it (it is not
part of our priority) but we will be glad to apply patches and to help
to see that coming.

I am wanting something like __FILE__ macro of C language. It should be 
useful in debugging and in managing a lot of data files and figures 
generated by different scripts.

The code you provided did not work as I wanted when multiple script 
files are nested. To solve this, slight modification is made:

[u,t,n]=file();
i = grep(n',"/(?:.*\.sci|.*\.sce)$/","r");
p = n(i(length(i)));   // <--- modified.

Still, this method does not give me the file name of *.sci itself. 
Suppose you have two files, fileA.sci and fileB.sce. A function is 
defined in fileA.sci and is called from fileB.sce. If you put the above 
code in fileA.sci and execute the script, fileB.sce, then you get 
"fileB.sce" in the varialbe, p.

Is there any way to get the file name of sci file as well?

How do I get the actual boundary values of an axis when the tight_limits
property of that axis is set "off"? The values in the data_bounds
property does not match the actual boundary values adjusted automatically.

The code provided above works only in scripts. It won't work in functions.
For functions, you may have a look at the function where(),
or/and whereami(), and get_function_path().

In scilab the  functions are not linked to a file name because it is 
possible to define a function in a script. Take also care that functions 
are Scilab variables (like matrices)

function n=functionname()
   [linenum,mac]=where()
   n=mac(2)
endfunction


example

function y=foo(x)
disp(functionname())
    y=x+1
endfunction

foo(3) //the calling function is named "foo"
A=foo
A(3) //the calling function is named "A"

Hi ! 

to my excuse I'm new in this. 
I want to use scilab on my SGI UV 1000  with 2000 Cores ,i download it
(the binary version)  everything ok, the parallel option seems ??? to be
installed so i try it but while i monitor the cpu i coudn't find out
that scilab is using more than 1 CPU. 
even the test says everything computet in different threads but ????. 
Did you have any Answere what i'm doing wrong, we just wanted to change
to scilab because matlab  wantet to charge us for 1000 cpu workers 70
000 Euro !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! and telling us that
Matlab is soo extremly performant just on this Supercomputer . Thats wy
we want to change. 

thank you

Hello,

Which OS are you using? On Windows, parallel_run() runs only 1 processor.
It is a limitation documented in the parallel_run help page.

Subject: Reading an Excel file with mixed strings and numbers
Message-ID: <CAOFcBYy2qQ=GzKJSwbRQXLBWY9Pt2h9oyGBs+wxQyFw1a9ciEA@mail.gmail.com>

I am trying to read an excel file that looks somewhat like this (only
a lot bigger):

Download Time 19:54:08	
Download Date 11-21-2010	
--------------------------------------------------	
11/21/2010 19:43:30	0

11/21/2010 19:44:10	0
11/21/2010 19:44:20	0
11/21/2010 19:44:30	518
11/21/2010 19:44:40	1139
11/21/2010 19:44:50	1035
11/21/2010 19:45:00	501
11/21/2010 19:45:10	449
11/21/2010 19:45:20	901
11/21/2010 19:45:30	545
11/21/2010 19:45:40	113
11/21/2010 19:45:50	1
11/21/2010 19:46:00	37
11/21/2010 19:46:10	17
11/21/2010 19:46:20	71


After I've read it I want to crop it according to a specific time and
keep the values in the second column.
However, when I do
[fd,SST,Sheetnames,Sheetpos] = xls_open('file.xls')
[Value,TextInd] = xls_read(fd,Sheetpos)

Value only contains *** in the first column, and TextInd mostly zeroes.

Any suggestions on how to get those timestamps?

Hi,

I have installed the 5.3.3 version of scilab on winXp but I'm not able to
use plot function.
What I got is the follow:
Exception in thread "AWT-EventQueue-0" java.lang.
UnsatisfiedLinkError: C:\Program Files\scilab-5.3.3\bin\jogl.dll: %1 is not

have somebody hear something similar?

Hi,

I look for a test of saisonality in time series.
The time series might be instationary and nonlinear and the saisonality
/ oscillation might have a changing amplitude. Furthermore the
distribution
might be unknown as well. 
I need something to test for significant saisonality without knowing /
estimating a (linear) model of the time series.

ideas I got so far: Chi Square Test for independency:
I could test for independence of saison and mean value of the data

Chi Square Test to test for different means of two data groups.
I could test for a difference of the mean between several seasons.

Any more or better ideas?

Thanks in advance, Stephan

I don't knwo if that is usefull for you:

I had to test seasonality and i did it successfully with Principal 
component analyses

you may use the grocer atoms toolbox to do PCAs

there's a lot of documentation on the web: 
https://www.google.com/search?q=seasonality+principal+component+analyses&hl=en

hi

i'd avoid using xls_open, which i found not very reliable with large files.
i'd try to save the excel sheet as a tsv file (text separated by tabs), 
then read it from scilab with read_csv, then sparse myself the date 
strings with an ad hoc function

let me know if you find dificulties

Was hoping not to have to do it that way, as I have a huge amount of
files and every little step I can avoid saves time.

Also read_csv seems to be extremely slow..
I tried reading a 30000 cells sheet, which took 460 seconds
Writing it as .sci and loading it again (after clearing) took 0.2 seconds.

Guess I could make a script to take care of that and reformat all
files during the night.

Did a quick search but couldnt find anything obvious. I suppose the
word you are looking for is seasonality - maybe that helps in finding
something useful.

Well, did you generate the excel files from another process? In that 
case, you may directly export your data as text.

About read_csv being very slow: you may try csv_read instead, which can 
be installed from atoms : http://atoms.scilab.org/toolboxes/csv_readwrite
It's supposed to be much faster

Also, if you do generate the excel files yourself, consider exporting 
numerical values only. If well formated, numerical text files may be 
read very quickly with fscanfMat

Finally, if the data acquisition takes long and you are going to test 
several scilab programs on it, i suggest you import the data to scilab 
once, then save it from scilab in a scilab-friendly format (with 
save("mydata.sav",data1,data2)), and then build your test programs from 
a load("mydata.sav"). This way, you wont have to read the whole data 
each time.
Oh, a last thing: string management was much faster with scilab4 (which 
does not support utf8), so this last "first acquisition and export in 
*.sav" could be done with sci4 (note that the instaler is less than 20MB 
and the sci4 instalation takes very few disk space)

Hi,

I don't know much about this application, but the Cepstrum can be used to
find hidden periodicity in time series.  Might be worth trying?  I have used
it for finding rotational components in the vibration signatures from
rotating machinery.  There's a simple example here
(http://www.dliengineering.com/downloads/cepstrum%20analysis.pdf).

Mike.

Although "seasonality" is not the term I use for long term trends hidden in
noisy data, I have had some success by taking the log of the data, and
running an FFT on the log data.  Usually, I have some prior knowledge of
the long-term periodic trends I expect, so it is relatively easy to
determine quickly if this method works.  Plotting the log of the data also
gives one a good feel for whether the data is stationary, or whether there
are windows of data that can be treated as stationary.  Any changing
magnitude effect is, of course, reduced when on works with logs, but such
effects can help one understand what the raw data is really telling you.

Hello Again !

Today i ran the example programm (the simple one with 
function a=g(arg1)
  a=arg1*arg1
endfunction

and
tic;res=parallel_run(1:2000, g);toc

while doing this i start top -u<user>
i couldnt see any parallel runs
so i start again 3 times 

the result was that the computer did't answere any more , we found out that
more than 9000 !!! processes iwere running we had to start the machine
again.(we have a SGI UV 1000)
I think the problem was that he started with nb_workers=0 which means take
every cpu and this 3 times.
Thats my first clue am i right. how default to start with 8 provessors ?
i also think that the command top didnt show me the right thing.

Hi,

 

sorry, of course I meant seasonality.

The time series consists of longer term trends, short term noise and
short time seasonality. 

oscillations / seasonality, if any, it is most likely to be nonharmonic.
I look for distinct frequencies.

When I did a FFT plot of the original time series there was noise only
in the spectrum.

I will give it a run with the differenciated series / the log of the
data. 

There is still the question how to test for significance of the found
seasonality. 

 

Stephan

What I inserted in the first mail is a cut'n'paste sample, Down to the
"------------------------------" its all text in one column.
Below that, it's two columns (timestamp in the first and the number to
the right in the second).

I attached the sample as an .xls file here too if that helps.

Hi ,

Good evening. I am a Scilab user and need help.

I am using, y = grand(10^6,90,'nor,0,1) to generate 90 columns and 1
million rows of normal distributed Random variables with mean =0 and std=1.

But I am getting following error: O=grand(10^6,90,'nor',0,1);
                                              !--error 17
                                            Rand: stack size exceeded (Use
stacksize function to increase it).

I used stacksize('max') but its not solving the problem.

Please help me in this regard. Thanks

Objet : [scilab-Users] Scilab Query: Related to stacksize


Hi ,

Good evening. I am a Scilab user and need help.

I am using, y = grand(10^6,90,'nor,0,1) to generate 90 columns and 1 million rows of normal distributed Random variables with mean =0 and std=1.

But I am getting following error: O=grand(10^6,90,'nor',0,1);
                                              !--error 17
                                            Rand: stack size exceeded (Use stacksize function to increase it).

I used stacksize('max') but its not solving the problem.

Please help me in this regard. Thanks

You may try with:

params = mlist(["plist" "nb_workers"],8);
tic;res=parallel_run(1:2000, g, params);toc

How much RAM do you have on your computer?
On mine, I need to crank up stacksize to 1e8 to calculate O, which eats 
up almost 1GB of RAM!
You may not have enough RAM...

Yes, but to test your case, the formating of data (dates) in the excel 
file is needed.
Dates are numbers + special format.

For me, it works:

-->[fd,SST,Sheetnames,Sheetpos] = xls_open('file.xls');
-->format(12)
-->[Value,trash] = xls_read(fd,Sheetpos);
-->Value
  Value  =

     40503.82801    818.     Nan

Then, you just have to convert dates according to the format you need,
either raw numeric as it is "hard-coded", or in a human readable way.
For example:

d = getdate((Value(4:$,1)-25569)*24*3600);
d(:,9) = d(:,9)+d(:,10)/1000;
d = d(:,[6 2 1 7 8 9]);
msprintf("%02i/%02i/%02i %02i:%02i:%02i\n",d(:,:))

(Amusingly, there is just a shift by 1 hour, likely due to the
European convention between summer/winter :-)

ok ... maybe I solved: I deleted the scinotesConfiguration.xml (which 
was an empty file) and the editor started again ...

let me run same script now

Hi Maso,

Could you attach your file 
C:\DOCUME~1\Maso\DATIAP~1\Scilab\scilab-5.3.3/scinotesConfiguration.xm ?
and after that just remove it should fix the problem (but I need to have 
the file to debug)

Regards

Calixte

[fd, SST, Sheetnames, Sheetpos] = xls_open('file.xls');
[Value, trash] = xls_read(fd,Sheetpos);
mclose(fd);
d = getdate((Value(4:$,1)-25569)*24*3600);

Subject: Scilab plot annotation is too small
Message-ID: <7D0AD7D3-B6E0-4C4E-AEB8-D26F165C1C24@knology.net>

I have generated some Scilab 2D plots and copied them onto MS Word at full scale. They are just fine. However, when I must compress the plots to fit a
double column page format the annotation also shrinks and is too small to be legible. 

I would like to tell Scilab to make the original annotation in a larger font. This is undocumented in the help menu.

I suppose you are taking about font sizes. You can change it by the 
following ways

1 for the current graphic window:
    ax=gca();
    ax.font_size=7;

    or
     ax.fractional_font="on";
     ax.font_size=6;//here font_size given in pt

2 for all subsequent graphic windows: (change of the parameter value in 
the ressource used to initiate the axes)
    da=gda();
    da.fractional_font="on";
    da.font_size=6;//here font_size given in pt


In the same manner you can also change colors , font_styles, .....

Serge,

Thanks for responding. However, the following code snippet failed in the calling routine:

ax=gca(0)
ax.font_size=10
exec('/Euler3/plott.sce',2);
plott(xplot,yplot,zplot,k);
The error message complained about the gca function. Should the snippet have been placed inside the plot routine itself?

Hal.

gca must be called without argument. If you want to specify a particular window you can do: scf(0);ax=gca() Serge Steer

Serge,

Scilab complained about the lack of an input argument.
 
scf(0);ax=gca(0);
                 !--error 58 
Wrong number of input arguments: This function has no input argument.

Another trick I have found that greatly reduces FFT noise it to temporarily
mask any localized "spikes" in the data (such spikes, with a narrow
temporal profile have a very broad spectral distribution).  One can also
try to eliminate any offset by subtracting the mean (or the geometric mean
or harmonic mean- the appropriate mean would be dictated by the nature of
the data).  This should hopefully reduce the scale of the FFT amplitude,
making it easier to spot any (especially low-frequency, or seasonal)
potential frequency components.

Well, in a sense Harold used '0' as an argument for gca()!  ;-)
A less confusing piece of advice would be:
"the function gca() should take NO argument".

Harold: facing the same situation then you, I tend to call gdf() and 
gda() at the very beginning of all the scripts I use to create plots:
hd=gdf();
ad=gda();
hd.the_propertie_to_change=the_value_that_fit_my_needs;
ad.the_other_propertie_to_change=the_value_that_fit_my_needs;
...

Thanks a lot for the input, will probably use some of this in the future
when I aim for a fully automated script.

I found my mainproblem now however, due to some formatting error every cell
in the excel sheet started with a ' .
After I removed that everything worked just fine :)

Why don't you chroot instead of dualboot?
This could be a more elegant solution, even if it's not perfect.

Anttoine-
My version of Linux (Ubuntu 10.04) will not allow me to install the two
libraries simultaneously on the same file system.  I have not considered
chroot- I don't know if it will find the alternative file system.  Worth a
try, I suppose.  Since I like to keep two instances of the entire distro on
my computer (one, my "working" system, one my "experimental" system)
rebooting has always been my "lazy" approach.  I'm not sure how to use
chroot in this process, since both systems have root named "/"...maybe
worth experimentings with.

-20CaCc+2Cb-0.2Cc

1. Develop code Runge Kutta of order 4 and one of Euler to solve the problem.2. If initial conditions are Ca = 500, Cb = 0, CC = 500. Halle concentrations for times ranging from 0 to 30 seconds3. Compare justify and interpret the results:

Filtering temporal spikes is a good idea, since there are some of them.
I will try that.

The data sample as around 7000 data points, the frequency I look for is
around 1/10 * sample rate.

 

May be there are methods that are better suited for identifying
frequency components in that kind of data?

FFT always describes the time series by harmonic oszillations, which
might not work well

if oscillations are not (strictly) harmonic.

 

What about wavelets (don't know much about it yet, though)?

Another trick I have found that greatly reduces FFT noise it to
temporarily mask any localized "spikes" in the data (such spikes, with a
narrow temporal profile have a very broad spectral distribution).  One
can also try to eliminate any offset by subtracting the mean (or the
geometric mean or harmonic mean- the appropriate mean would be dictated
by the nature of the data).  This should hopefully reduce the scale of
the FFT amplitude, making it easier to spot any (especially
low-frequency, or seasonal) potential frequency components.

Hi,

 

sorry, of course I meant seasonality.

The time series consists of longer term trends, short term noise and
short time seasonality. 

oscillations / seasonality, if any, it is most likely to be nonharmonic.
I look for distinct frequencies.

When I did a FFT plot of the original time series there was noise only
in the spectrum.

I will give it a run with the differenciated series / the log of the
data. 

There is still the question how to test for significance of the found
seasonality.

Although "seasonality" is not the term I use for long term trends hidden
in noisy data, I have had some success by taking the log of the data,
and running an FFT on the log data.  Usually, I have some prior
knowledge of the long-term periodic trends I expect, so it is relatively
easy to determine quickly if this method works.  Plotting the log of the
data also gives one a good feel for whether the data is stationary, or
whether there are windows of data that can be treated as stationary.
Any changing magnitude effect is, of course, reduced when on works with
logs, but such effects can help one understand what the raw data is
really telling you.

Did a quick search but couldnt find anything obvious. I suppose the
word you are looking for is seasonality - maybe that helps in finding
something useful.

Better stick with DFT, smoothed DFT or try seasonal adjustment freeware
Demetra+   - that's what official statisticians might do.

Well, we use it at work (I have to admit I was not the one setting it 
up) and it's quite convenient.
Basically, the only common points between your two systems will be the 
linux kernel.
Apart from the kernel, the two systems are totally independent and have 
their one filesystems.
We use it to run a debian distro (that have nice packages for 
electromagnetic simulations) on a centos system (needed for a lot of 
other simulations softwares).
Switching from Centos to Debian is as easy as "/local/chroot/debian" and 
it's even easier to switch back: "exit".
We didn't bother setting up the X server on Debian (the softs we use are 
command-line only) but it might be possible to share the same X server 
on both systems.

Cheers,

Antoine

Did you already try Scilab2C
(http://atoms.scilab.org/toolboxes/scilab2c/1.1)?  If so, what problems did
you have?

Mike.

Subject: Returning matrix of unknown dimensions from C library
Message-ID: <4ECA524B.8080001@laas.fr>

Hi everyone,

I am trying to extend scilab using a C library (libtiff to read 16bits 
tiff images).
I have a problem using ilib_for_link/call:
Is there a way to call a C function that returns a matrix without 
knowing a priori its width and height?

Cheers,

Antoine

Antoine,

One solution is make a script that calls two functions in your C 
library. The first external function call returns the dimensions, the 
second one gets called with an allocated matrix of the proper size and 
sets the data,

Best wishes,

Jasper.

Thanks for your quick answer.
That's what I am currently doing, but I was wondering whether I could 
find something a bit more elegant!

Just gave chroot a try- works nicely, but my system won't let me run a
second X server, which seems to limit the second root to command line
only.  Useful, but not much imporvement over my reboot approach.  Note that
I can access files on either system from whatever system is active...I
could run Scilab from the command line on the new root, but, since Scilab
comes installed and configured on my preferred distro, I really have no
need to do this.

What I use the dual boot system for primarily is to have an "experimental"
system where I can try out new software, check for conflicts, etc. before
adding it to my "working" system.  As time goes on, my "experimental"
system starts looking more like my "working" system- when it seems stable
enough, and has all the critical functions I need, I then start using it as
the "working" system, and the old system is discarded and a new base distro
can be explored without causing problems.  This also gives me the chance to
evaluate new releases of projects like Scilab without losing my existing
capabilities.

The conflict between the libgl versions that I encountered actually
occurred when trying to run Dassault Systemes' DraftSight2 (latest release)
on the same platform as Salome.  Not being to fond of the idea of rebooting
to switch between systems to resolve library conflicts, and the fact that
an older version of DraftSight2 plays nicely with Salome, and the fact that
Salome is by far the more important package, Salome wins.  I am not sure I
could easily make the same choice with Scilab requiring a different library
version- although rebooting to run Scilab is not nearly as unpalatable as
the other two, since I seldom, if ever, need to run Scilab when I am
running Salome.  The question is, are ther atoms that rely on one version
of the libgl library while other atoms rely on the other version?

This is a conflict I have never encountered on Linux before, but, I suspect
that, with the "desktop wars" between Gnome 3 and Unity running rampant, I
suspect we can look for more such conflicts in the future...

Stephan-
Sounds like you are working with data sets that resemble some that I work
with frequently.  About the same size, non-stationary seasonality (which I
prefer to call low-frequency periodic trends), high, non-stationary
temporally variable "noisy" signals.  I usually have a priori knowledge
that there is likely aliasing due to the fact that I am limited in sampling
rate vs. total time period (varying the sampling rate for different
collection instances can sometimes resolve at least part of this issue).  I
haven't figured out how to get the aliasing out of the system, although
there should be some way to do this based on "unfolding" the spectrum.

Anyway, the approach I take is this.  Starting with a COPY of the raw data,
I run it through NIST
Dataplot<http://www.itl.nist.gov/div898/software/dataplot/>to get a
feel for the data, using what they call the 4-plot.  This gives me
a feel for the periodicity, auto-correlation, statistical distribution, and
helps me identify the "ouliers" (i.e., spikes, 0's, any data point that is
"unusual"), which are then filtered out by replacing specific data points
with a "more reasonable" value (which is why I use a copy of the raw data,
rather than the original).  Usually use a spreadsheet for this.  I might
run the data through Dataplot a couple of times to evaluate the effects my
"filtering" have had.  Usually, still in the spreadsheet, I next remove the
"DC offset" by subtracting one of the Pythagorean
means<http://en.wikipedia.org/wiki/Pythagorean_means>.
Which is appropriate depends on the nature of the data.   This reduces the
low end of the spectrum, which is where the "trends" are located.

For the Fourier analysis, I could stay with Dataplot, but I find it much
easier to extract information from the Scilab approach.  Furthermore,
Scilab offers an alternative DFT processcalled MESE.  The Maximum Entropy
Spectral Estimate (MESE), designed to produce high-resolution, low-bias
spectral estimate (refer to page 128 of the *Signal processing With
Scilab*<http://wiki.scilab.org/Tutorials%20archives?action=AttachFile&do=view&target=signal.pdf>manual,
or available
here <http://wiki.scilab.org/Tutorials%20archives>). MESE incorporates no
information in the estimated spectrum about the autocorrelation lags. That
is to say that the bias resulting from the leakage from the window
sidelobes should be eliminated (or at least minimized in some sense).   In
other words, one tends to get cleaner "spikes" in the spectrum.  It is much
easier to pick out the lower-frequency components of the signals with this
procedure.  One then subtracts these components from the working data, and
repeats the process.  Ideally, you have extracted all of the available
information from the data when the residual is Gaussian white noise (a
point I have never actually reached in practice).

I don't believe "windowing" techniques will work with low-frequency
components, although I could be mistaken in this.  I have toyed with
windowing when I have reduced my residual to what has the appearance of a
frequency-modulated signal- but, then, I am looking to characterize such
events.  The information you are trying to extract will ultimately dictate
what approach you take.

I am attaching a "working document" that I have put together giving more
detail on this approach.

[..]

It depends what you want to do.
Scilab has several ways to use this kind of architecture:
* As Samuel said, parallel_run is one way [0]
* Under Linux, we do no ship with MKL, Gotoblas neither Atlas (but with
a very slow refblas). If you switch to one of them you will get both
great performances and all core being used during matrix computations.
* GPGPU: you can give a try to our GPGPU extensions (don't hesitate if
you have any feedback). [1]
* If you are more into grid/cloud computing, you can give a try to proactive
[2]
* In Scilab, even it is a bit outdated, you will find a PVM interface [3].
* Finally, if you are familiar on the build process of an linux application,
you can try with the MPI implementation of Scilab (in the git branch "MPI")

Hope this helps,
Sylvestre

Dear Sylvestre ! 

Thank you for the reply I'm using scilab on a SGI UV 1000 with 2000
cores 
I try the example programm  with no params that's why i chrashed , yes
ok, but how can i prevent the users to do the sane as i did . Currently
i try with limit maxproec 128  (not 16 000 as default parameter)  on the
command line.I didnt test it right now becouse i have to be sure that
nobody is on the machine exept me otherwise :-( my boss will cut me into
pieces. 
Do you have aby other sussestion ?? 

thank you

[..]

It depends what you want to do.
Scilab has several ways to use this kind of architecture:
* As Samuel said, parallel_run is one way [0]
* Under Linux, we do no ship with MKL, Gotoblas neither Atlas (but
with
a very slow refblas). If you switch to one of them you will get both
great performances and all core being used during matrix computations.
* GPGPU: you can give a try to our GPGPU extensions (don't hesitate if
you have any feedback). [1]
* If you are more into grid/cloud computing, you can give a try to
proactive
[2]
* In Scilab, even it is a bit outdated, you will find a PVM interface
[3].
* Finally, if you are familiar on the build process of an linux
application,
you can try with the MPI implementation of Scilab (in the git branch
"MPI")

Hope this helps,

Sylvestre

By the way, did you try modules to get both libraries at the same time?
( http://modules.sourceforge.net/ )
It is installed on a cluster I have access to and it's quite efficient.
Basically you can do things like "module load gcc/3.1.1" and "module 
load scilab/4.1.2" to get gcc3.1.1 and scilab4.1.2 as your default 
compiler and scilab exe in the current terminal.
I use it to run simultaneously different softwares that have 
incompatible requirements.
It may be a solution for you.

Cheers,

Antoine

Hello,

is there a module written for Scilab dedicated to a quick import of
meteonorm file format ?

Thanks,

Modules looks like a VERY useful tool.  Thank you.  Have to give it a try
when I switch to the "experimental" platform!

Readers,

Is there an existing library in xcos similar to simulink
simpowersystems module. If not, is it possible to create a similar
module in xcos?

Sorry about that.
Could you do the following ?
sudo dtruss -f /path/to/bin/scilab-cli 2> trace.log

and upload somewhere the log file ?

Thanks

Hi there:

 

I am new to SCILAB. It has been suggested to me by a friend of mine. I am a
head of a small R&D department and my prime focus is the generation of new
concepts for algorithmic trading. I am trying to use Scilab for some
statistical modeling primarily based on Random Walks. Unfortunately, after I
have installed Scilab on my Windows 7, 64 bit machine I am getting an error
that tells me that I have no permissions to save my files? It's a bit
discouraging especially because I could not find answers to my problem in
any Scilab forums. I was hoping that you could help me.

 

Cheers,

 

Dr. Alex Bogdan

Hi,

First, are you sure that you have permissions to save files in this 
directory ?

Can you provide a small example to see what you do and what is the full 
error message ?


A example to read/write a file in scilab:

mputl('Hello', TMPDIR + "/test.txt") // we write in TMPDIR
mgetl(TMPDIR + "/test.txt")

Thanks

Allan

Hello.

I had the same kind of problem with Windows Vista and the solution was to
isntall Scilab outside the default folder Program Files.

It is also possible that you are trying to save the file in scilab software
directory.
Generally one should use separate folder where you have access to store the
data.

So when you choose the option `save' check that you have write permissions
in which folder you are asking to save for.

Otherwise change the folder to the folder like My documents where one may
have write permissions.
This problem is not due to  Scilab,  it is due to local setup or on
individual machine it is due to Operating system you are using.

Subject: ploting planck's function
Message-ID: <4ED23D32.5000107@ac-toulouse.fr>

Hello,

I teach mathematics in a lyc?e, and I would like to use scilab to plot 
curves.

I was trying to plot the planck's law function, but I do not have the 
expected curve, this might be due to precision problems.

We have f(l)=(2hc^2/l^5)* 1/(exp(hc/(ktl))-1) 
(http://en.wikipedia.org/wiki/Planck%27s_law)

l is the wavelength.
T=1000 (temperature).

and c=3e8, k=1.3e-23, h=6.3e-34.

The curve I get is increasing, and looks like a parabola, wich is false, 
obviously. I get a better result with maxima, by the way.

Does anybody know how to increase the precision?

best regards

I had the same problem with windows xp, on a network. Scilab's default 
directory does not seem to be set to the user's one, but somewhere in 
the installation tree, or in the local machine.

I suppose you have to defined f in scilab like this :

function y=f(l)
   T=1000,c=3e8,k=1.3e-23,h=6.3e-34
y=(2*h*c^2/l^5)* 1/(exp(h*c/(k*t*l))-1)
endfunction

(do not forgot the products *  !) then you have to evaluate f on a set
of point


l=[1:0.01:10]// becareful to l=0 !!!
y=feval(l,f)

then you can plot the curve and had grids or ...

plot(l,y,'-r')
xgrid(3)

remind that scilab use a floating point representation of reals numbers
with 1e-16 relative precision so that  : k=1.3e-23=h=6.3e-34=0 compared
to c=3e8 !!!

since maxima use  symbolic calculus it can perform arbitrary precision
calculus.

use a unit system where k=c=h=1 (and rescale results after calculations
....).

OK thank you very much, it works well, the curve is OK.

Yet, I cannot anderstand why
  plot(l,f(l)),
which is the comamnd I used before, still gives me a false result.

because the way you have defined f(l), l is a 1x1 matrix but when you
want to estimate f(l), l is a 1xn matrix so scilab is confuse with * and
/ in f definition since this operations are not "element wise" for
matrix ... then you have two possibilities :

- replace * by .*, / by ./  in f definition
- use feval(l,f) instead of f(l)

Hi there
I can't open Scilab (with java GUI).
When trying to open Wscilex, I get:
"Scilab ne peut pas cr?er la classe principale Java Scilab (nous n'avons 
pas ?t? capable de trouver la classe Scilab principale. V?rifier si les 
paquets Scilab et thirdparty sont accessibles)."

I've been able to start scilab without problems for months, but suddenly 
it does not work.
I tried to reinstall scilab, no success

Attached to the mail is debug info from Scilex,

Any idea?

Seems like that file becomes bugged sometimes in severla OSs. I had to
remove mine to start scilab after a crash (running ubuntu 10.11, 64 bit).

Merci St?phane.
Clearly, the problem is here:

dyld: Library not loaded: /usr/lib/libncurses.5.dylib
  Referenced
from: /Applications/scilab-master-1322152505.app/Contents/MacOS/bin/scilab-bin
  Reason: no suitable image found.  Did find:
	/usr/lib/libncurses.5.dylib: mach-o, but wrong architecture
	/usr/lib/libncurses.5.dylib: mach-o, but wrong architecture


Could you try to rename it ?
mv /usr/lib/libncurses.5.dylib /usr/lib/libncursestmp.5.dylib

I guess it is a system that you upgraded and not a brand new one?

Subject: Color with a LaTeX string
Message-ID: <1322604973123-3546663.post@n3.nabble.com>

Hello,

Could you help me to use properly the following command
'$\textcolor[rgb]{r,g,b}{Hello}$' in a xstring or xtitle where r, g and b
are given by a *colormap* (eg : ens_color=floor(255*jetcolormar(100));
r=ens_color(10,1); g=ens_color(10,1); b=ens_color(10,1)).

Thank you.

This is a LaTeX question. r,g,b must be between 0 and 1, not 0 and 255.

Ok but the argument [rgb] does not seem to be recognized.

eg : the expression xstring(0.5,0.5,'$\textcolor[rgb]{0,1,0}{Hello}$') give
*/rgb]0,1,0Hello/* in the plot window but
xstring(0.5,0.5,'$\textcolor{green}{Hello}$') word good.

The problems is that I don't know the name of each color in the colormap...

Thank you.

For now, you have two solutions:
i) \definecolor{MyGreen}{rgb}{0,1,0}\textcolor{MyGreen}{Hello World}
ii) \fgcolor{#00FF00}{Hello Wolrd}

In a next release of JLaTeXMath, it would be possible to have 
\textcolor{0,255,0}{Hello}.
