Subject: Installation issue with Scilab-5.0.3
Message-ID: <904D6C01-31F2-42C8-8CCC-400806FCB732@cchmc.org>

Hi,

I have tried to install Scilab 5.0.3 on my OpenSUSE 10.3 system (and  
also tried to compile from source), but when I try to invoke scilab  
binary after installation, I get

Warning: Could not find Java package '/usr/local/src/prakash/scilab/ 
new/newscilab/scilab//modules/helptools/jar/ 
org.scilab.modules.helptools.jar'.
Some problems during the loading of the Java libraries occured.
This could lead to inconsistent behaviours.
Please check SCI/etc/classpath.xml.
Could not create a Scilab main class. Error:

         at org.scilab.modules.jvm.Scilab.<init>(Unknown Source)

Scilab cannot create Scilab Java Main-Class (we have not been able to  
find the main Scilab class. Check if the Scilab and thirdparty  
packages are available).

Any idea how this can be resolved?

Thanks,
Prakash

Dear Mr/Ms

Would you please tell me if SciLab is "similar" to Mathematica software. I am  a teacher at University of Azores (Portugal). In fact,  I need Mathematica to support proofs in a Theory of Computation course. However, I think SciLab could be a good alternative, since it is free but only if it is compatible with Mathematica. In your web site you just mention MathLab. 

Sincerely,

Helia Guerra

Hi guys,

I am trying to run the following code in scilab:


L=3; M=2; fs_in=6; Ts_in=1/fs_in;
t_in=[0:Ts_in:5];x_in=sin(2*%pi*t_in)+2*cos(4*%pi*t_in);
getf("spfsr.sci");
getf("firpm.sci");
x_e=expander(x_in,L);
t_cont=[0:0.01:5]; x_cont=sin(2*%pi*t_cont)+2*cos(4*%pi*t_cont);
h=L*firpm(60,[0 2/(fs_in*L) 4/(fs_in*L) 0.5]*2,[1 1 0 0],[1 1]);
x_ef=rtitr(h,1,x_e);

Does anyone have any idea as to why rtitr is giving me the error?

Hi guys,

I am trying to run the following code in scilab:


L=3; M=2; fs_in=6; Ts_in=1/fs_in;
t_in=[0:Ts_in:5];x_in=sin(2*%pi*t_in)+2*cos(4*%pi*t_in);
getf("spfsr.sci");
getf("firpm.sci");
x_e=expander(x_in,L);
t_cont=[0:0.01:5]; x_cont=sin(2*%pi*t_cont)+2*cos(4*%pi*t_cont);
h=L*firpm(60,[0 2/(fs_in*L) 4/(fs_in*L) 0.5]*2,[1 1 0 0],[1 1]);
x_ef=rtitr(h,1,x_e);

Hi all,

I have to export some data structures like

a.a = zeros(1,2);
a.a.a = 'a.a.a';
a.b.a = 'a.b.a';

in Matlab.


The savematfile does not work.

I can resort to writing a matalab m file which reads the scilab binary 
format. Of course I don't want to start from scratch and I am looking 
for the scilab function that loads the file.

That function is "load" at the command line, but I am not able to find 
its code.

Can anybody tell me where can I find the code of the "load" function?

Cheers,
  Anton

In your example the first two arguments should be polynomial not a scalar
vectors.
 
try this :
After : h=L*firpm(60,[0 2/(fs_in*L) 4/(fs_in*L) 0.5]*2,[1 1 0 0],[1 1]);
hp=poly(h,'x','coeffs');
1p=poly(1,'x','coeffs');
 
Then : x_ef=rtitr(hp,1p,x_e);

Hello,

Since I have installed Mixmod toolbox, I can't no longer access to the help
browser. I believe I don't install mixmod well because scilex give me this
error :
>Can't go to directory /UTIL/SCILAB/helpMixmod
 !--error 998
chdir: Internal
Error
at line       8 of function rescan_helps called by :

line    25 of function run_help called by :
line    20 of function browsehelp called by :
line     7 of function help_menu called by :
help_menu(1)
while executing a callback

I don't want to reinstall all (scilab and the toolboxes I use). I prefer to
manually change  the path in the right file.

Thus, if  you could tell where I can find this file, I'll be grateful

Stephane

Hello

I do not use any additional patches from debian science.
I am just using the sources I get with apt-get source scilab
when I inserted your repository in /etc/apt/sources.list

I am using sbuild which opens a clean chroot to build the
packages there.

Subject: regexp returns wrong indices
Message-ID: <993905.80570.qm@web28312.mail.ukl.yahoo.com>

Hi,
Using the regexp-expression in order to check whether
several sub-strings occur in a given string , start
and stop indices may be wrong due to shifting.

I.e:


Order

->[a1,a2]=regexp('.MEAS TRAN  DERIV y(i) WHEN y(i) <= x(i) RISE= TD=-4','/\.MEAS|TRAN|FIND|DERIV|WHEN|CROSS|RISE|FALL|TD/')


yields result:


 a2  =

    5.    9.    17.    26.    45.    51.
 a1  =

    1.    6.    13.    23.    42.    50.

This suggests  that the second sub-string which matches (TRAN) starts already at column-position 6 and ends at 9,
whereas the right result is: start at column #7 ,end at column #10.

Thank You,

Ralf Kuschel

I have data in a CSV (Comma Separated Value) format. I would like to
load this data into Scilab to manipulate. The load function that I found
only loads previous session variables. Is there another load function
that can load in raw data in a CSV format?

The function fscanfMat works very efficiently provided the data elements
are separated by spaces or tabs. If you have the more common comma
separation you are stuck (AFAIK) with iterating through the file one
element at a time.
This is effective, but excruciatingly slow.
If you are using Unix you can use the 'tr' command to change commas to
spaces, but that is not portable to Windows unless you have cygwin
installed.

Yep, on the website:

For GNU/Linux platforms [xxxx] [64 bits]

Same as under 32 bits.

I don't understand this point.

You have to add the option --enable-build-localization

Try: --enable-build-help

64 bits gluegen-rt.so should be available in <SCI>/bin/
If you are sure that it is OK, try to launch Scilab this way:
SCIVERBOSE=1 ./bin/scilab 
and check if the LD_LIBRARY_PATH contains <SCI>/bin/

I don't think that is linked to the problem you currently have.

What you do mean by "run anything" ? 
Any computation like 2+2 are crashing the application ?

The function fscanfMat works very efficiently provided the data elements
are separated by spaces or tabs. If you have the more common comma
separation you are stuck (AFAIK) with iterating through the file one
element at a time.
This is effective, but excruciatingly slow.
If you are using Unix you can use the 'tr' command to change commas to
spaces, but that is not portable to Windows unless you have cygwin

I have data in a CSV (Comma Separated Value) format. I would like to
load this data into Scilab to manipulate. The load function that I found
only loads previous session variables. Is there another load function
that can load in raw data in a CSV format?

Sylveste, I tried the 64 bit Linux build this evening, and it's very  
close . Again scilex works fine but graphics is broken. Problem  
appears to be some 32 bit libs in scilab/lib which break the loader in  
a pure 64bit environment . Problem libs are gluegen-rt, jogl_cg, jogl  
and jogl_awt

Subject: Histograms and error bars
Message-ID: <60781.83.202.112.23.1228991815.squirrel@keo.limsi.fr>

Hi everyone,

I would like to plot an histogram to compare 5 experimental conditions.

For example let's say that I have 4 classes and 2 experimental conditions.
Therefore I have a 4*1 vector "classes" giving the classes and a 4*2
matrix "average" giving the average for each class and each experimental
conditions.
Then:
--> bar(classes, average)
does the trick.

The problem is that I want to plot error bars for each class and each
experimental condition.
I know how to do that with a single experimental condition with the
"errbar" function because in this case I know the x and y position of each
bar (x is given by "classes" and y by "average"). But with several
experimental conditions, each bar has a different x position. "bar"
internally compute this x position but I cannot access it so I cannot use
"errbar".

Does anyone have an idea?
Is there a way to "attach" errors to data and automatically plot them?

Thanks in advance,
Mathieu

Subject: Graphic images
Message-ID: <4943EA2E.8060104@durietz.se>

I have tried to make image files of graphic windows in 
Scilab 4.1.2 (Win XP).

-->xs2gif(0, filename+".gif")

works (creates a GIF-file of figure 0), but the y_label is 
wrong: The text line but not each letter is rotated -270 
degrees. Apart from this everything is OK.

-->xs2ps(0, filename+".ps")

also works, but I cannot open the PS-file in my PostScript 
program GSview (lots of errors). I understand that I have to 
do something more with the file but have not been able to 
manage it...

If (from the graphic window menu) I choose

1. File - Export - Export type: Postscript

I can open the resulting EPS-file in GSview but the 
proportions of the axes are changed and the y_label is 
partly outside the "paper".

2. File - Copy to clipboard - Bitmap

and paste it in a GIMP image of the same size, the 
positions of all labels and tick_labels are wrong (and the 
image therefore useless)!

All this worked in Matlab. There it was also possible to set 
the 'PaperPosition' of the figure. Is there anything like it 
in Scilab?

I would be very happy if anyone could tell me how to manage 
this!

Regards
Stefan

OK, maybe you will be interested by:
http://wiki.scilab.org/Graphical_issues_with_Scilab_5.0

I was asking about the version 5 because the graphic export completely
changed in this version.

Thank you for the link, which I read.

I tried again to update my graphic card drivers - much
trouble and limited success and it takes a lot of time...

I installed Scilab 5.0.3, but when I run it (it introduces
itself as 5.0.2!) it takes three minutes to create
a figure the first time and all my other applications slow 
down as well.

And the figure is worse from the beginning than in Scilab
4.1.2: it is upside down, dots and lines don't fit (even
worse than after making a GIF from Scilab 4.1.2!) although
the dots are at least round.

So, if the figure is worse from the beginning in Scilab 5,
it does not matter if the export is better.

Hi,

I'm trying to read longer wave file (in CD quality, normal single). It seems

Wrong argument 2.

at line     103 of function wavread called by :

On same PC, matlab loads that file without any problems. What am I doing 
wrong ? Any reliable and robust wave reading SW ?

Thanks in advance,

What kind of number is that at the bottom...(4.406D-16).

Thanks in advance.

Hi,

experiment :

-->0.00000001
 ans  =

    1.000D-08

-->1d-6
 ans  =

    0.000001

So it's just a power of ten.

in your case, you can consider 4.406D-16 as zero.

You have to take care of precision in your operation.
Scilab isn't a symbolic software.

Dear Scilab user group

exists there may be a toolbox (like the swarm simulation framework) or an example demo for evolutionary simulation or an animation example?

thanks in advanced

Note that Scilab 5 is results closer that what you expect:

-->a=[1 1 3
-->1 2 3
-->0 1 1 ]
 a  =
 
    1.    1.    3.  
    1.    2.    3.  
    0.    1.    1.  
 
-->p= poly(a,"z")
 p  =
 
              2   3  
  - 1 + z - 4z + z

My bad, I tried with different numbers than you :/
(btw, please, copy and paste instead of a screenshot next time).

Then, Michel's answer is much better than mine!

Sylvestre,

his matrix was :
A=
1 1 3
1 2 4
0 1 1

in short term,

the poly of this matrix is : det( I*x - A) = x^2*(x-4)
solution by hand of course, and i don't see myself do it on a 1000*1000
matrix.

under my Scilab 4.12 :   5.121D-16 + 2.902D-16x -4 x^2 + x^3

under my Scilab 5.0.3 :  - 7.019D-17 + 1.792D-15x - 4x^2 + x^3

Regarding A, i assume that all value almost at zero are zeros.
i mean, det(A)=0 so at least zero is a root of   my "poly" and i assume at
least that 5.121D-16 is "zero" or - 7.019D-17.

A famous Scilab alternative do that also but you have to take care of the
truncation of the values in this case.
>> poly(a)
ans =

    1.0000   -4.0000    0.0000    0.0000

"good" result in this case, but if i assume that in my matrix, the zero is
now 0.000001, it's now a wrong result.

OK, maybe this difference is caused by the change of precision that we
introduced between Scilab 4.X & 5.X:

Dear Sharad

you can find swarm under www.swarm.org. I am just interested to know if there something similar available for scilab? I am looking for a bank economic simulation framework - something similar already exists for artificial stock market simultation, see http://artstkmkt.sourceforge.net/ 

Best readards and happy Christmas

Bonjour Thierry

En aucun cas, ceci est un probl?me de performances de ton PC, mais 
plut?t une instabilit? de Windows
Ceci dit si tu d?sires faire du calcul plus pouss? et m?me pour d'autres 
chose, passer ta m?moire ? 1GO
ne sera pas du luxe ;-)

Essaye ?galement de d?sactiver certains programmes qui se lancent au 
d?marrage avec msconfig, juste
le temps d'un temps d'un test :
"D?marrer > Ex?cuter" puis saisit "msconfig" et "OK", clique ensuite sur 
"D?marrage s?lectif" puis d?coche
la case "Charger les rubrique du d?marrage" [n'ayant pas un XP sous la 
main, je ne suis pas s?r du libell?]),
tu fais ensuite "Appliquer" puis "Fermer", il faudra red?marrer. Si cela 
en change rien, r?tablit le msconfig
en cliquant sur "D?marrage normal" ce coup-l?. (il faudra encore 
red?marrer !).

Tu peux aussi vider ton dossier C:\Windows\temp en mode sans echec si 
possible. (? faire souvent d'ailleurs...)

Sinon, essaye-d?j? de d?sinstaller Scilab et de le r?installer avec les 
anti-virus et firewall d?sactiv?s,
puis de le faire fonctionner toujours avec ces programmes (qui sont des 
bouffes ressources) d?sactiv?s.
Est-ce que cela ne survient qu'avec ton fichier ? en as-tu essay? 
d'autres ? ceux livr?s en exemple ?

A plusieurs reprises et avec diff?rents logiciels, il m'est arriv? avec 
XP de voir une application quitter
sans raison et sans message (acrobat, filemaker, ie 7, etc.).

N'ayant pas parcouru, tous les autres messages, je ne pourrai pas de 
donner d'autres "manips" ? tester.

Voilou

Message-ID: <GCEPLKNAIDEJKBMCDBGAGEFICBAA.th.boucher@tele2.fr>

Hello, 
At first, excuse me for using the French language...
I just sent an email to the forum to ask for advice, because after beeing installed, the Scilab 5.0.3 software didn't work on my computer (processor: Intel Pentium 4 - 2,54 GHz, RAM 512 MB, OS: Windows XP SP3). As soon as I loaded the demo ".sce files" from the Scilab site and sent one of them to the software for computation, the main windows disappeared... Apparently, not enough RAM in my computer...
Thank you very much Peter (alias Foncteur) for your advices : I already tried some of your tricks:
What doesn't work (or isn't enough):
- Windows XP "Selective starting" with Scilab 5.0.3 software.
- cleaning of C:\Windows\temp directory.
- Virusscan removal after Scilab removal.
What seems to work:
- using Scilab 2.6 or Scilab 4.1.2 (but not 5.0.2).
- using Scilab 5.0.3 software in "safe-mode".
Now, I'm thinking of increasing the RAM very soon.
Thanks to you for your help.
Thierry

I have now at last succeeded in updating my graphics card
drivers, thanks to help from ATI support.

But my Scilab 5 figures do not get better. I had a faint
feeling that my problem was due to bad precision in Scilab
5. I use datenum() to convert date vectors to time numbers 
that I can plot in figures. I plot my data with "stems", 
i.e. vertical lines, terminated with round dots, from a 
baseline. Bad precision in the x values of the different 
polylines (vertical lines and dots) will result in the 
errors I described.

After having read the mail 2008-12-17 15:29 from Sylvestre:

"OK, maybe this difference is caused by the change of
precision that we introduced between Scilab 4.X & 5.X:
http://wiki.scilab.org/Scilab_precision"

I tried to make the year zero in my date vectors before
converting them with datenum() and the problem disappeared!
But in Scilab 4.1.2 it worked anyhow.

A second issue: The dotted lines are even worse in Scilab 5
than in Scilab 4.1.2 (and in Matlab...): the dots are longer
dashes. Can anyone tell me where to fix this in the source
code (I have a working function but it is very long)? 
Strangely enough this improved with  Export - GIF...

A third issue: How can you change the position of the figure
in  Export - Postscript  (Scilab 4.1.2)? I have searched for 
info on this (but probably not enough...). In Matlab you 
have the figure property 'PaperPosition'.

Regards
Stefan

Technically, on the overall (ie, if you don't consider new bugs),
Scilab's precision under Linux 32 bits improved since we moved from
extended to double precision.


Can you show the precision issues that you are getting ?

But I am using Windows XP (at the moment...).

Maybe it is in the graphics after all: I use the same 
numbers f?r the x-values of both polylines, but they differ 
in the figure anyhow.

Well, the url on the wiki about precision only occurs under Linux 32 bits. ;)
Under Windows, numerical results should be the same from version 4 to 5.

Can you report a bug on http://bugzilla.scilab.org/ with your code, the
output with Scilab 4 and 5 ?

Hi

First of all, congrats for making this software available ! Great work !

I'm currently facing an issue regarding a simple BandPass filter...

Here's the code (FYI, I'm a total newbie - Forgive any 'basic' error !) :

[voice, Fs] = wavread("test.wav");
nbSamples = size(voice, 2);
if (size(voice, 1) > 1)
   voice = voice(1, 1:nbSamples); // Use only one channel if recorded in 
stereo
end;
lisys = iir(11,'bp','butt',[300/Fs 3000/Fs],[0 0]);
voice = flts (voice, lisys);
wavwrite(voice, Fs, "voiceFiltered.wav");

Scilab doesn't complain. It just doesn't work. What's wrong ? A similar 
LP filter works, but an HP doesn't, too. I certainly miss something...

Thanks and regards !

Hi,

may you be so kind to send us the "test.wav" file that you are using ?

Windows / Linux / what Scilab version ? 

I would like to reproduce EXACTLY your test condition ...

You can download here http://f6fvy.free.fr/scilab/bpfIirButt.zip the 
test file, with a tiny test script ;-)

Actually, I found by chance that the filter order must be <= 6 to work 
in these conditions. When using a greater order, it doesn't work.

WinXP SP2 + Scilab 5.03

In Scilab 5, even the x-grid lines don't fit the x-ticks! 
And the axes are displaced. It is all very evident in my 
plot with original x-data.

Hi,

one of our student found that those two examples below don't produce same 
result :

1. -->k = 0.5 * 44100 / 343;
    -->k = k / 44100 * 343;
    -->acos(k/0.5)
     ans  =

    2.107D-08i

2. -->k = 0.5;
    -->acos(k/0.5)
     ans  =

    0.


Same happens under 4.1.2 and 5.0.3. Any hint ?

Thanks in advance,

regards,

Rob.

FAQ.
Scilab makes numerical computations.
These are subject to rounding errors.
Other softwares make exact calculations.

Dear Mr/Miss

This is my problem; i have this equation :

v1=v+alpha*dk,

where dk=[ 0; 2.479D-62; - 1.324D-64; - 2.479D-62;1.324D-64],
alpha=1.

But after to solve the equation I obtained v1=v.
Why?, somebody could assist me?

Thanks in advance

It would be such a relief if you would turn your text below into a FAQ 
page on the wiki so that we could point users to that page whenever 
they complain that 1.2D-19 is not zero, which happens twice a week or 
so...

Would you do that for the community? Please keep the stamp "Best 
viewed with a brain", it's so true (and btw I can't believe that the 
original post starts with "one of our student found that..." - Is this 
a report from a teacher, then???).

http://wiki.scilab.org/

IMHO a FAQ page would fit nicely in the "Scilab documentation" 
sub-area (upper left tile of the table in the above page).

Do you take it?

Some quick news from the free community.

= Sagemath =
A Experimental "Scilab/Sage package" is planed for Sage 3.4 and an
experimental package by Jaap Spies is available here:
http://trac.sagemath.org/sage_trac/ticket/4821

= Mandriva =
Tomasz Pawel Gajc (a regular Mandriva contributor) created a package
available here:
http://sophie.zarb.org/viewrpm/9fa2afb865a5d83f04c8fb044af68214

= Opensuse = 
A Scilab package for Opensuse has been created by Andrea Florio.
It is available here:
http://packman.links2linux.org/package/scilab/80519
and should be included in the next version of opensuse

Note that Mandriva & Opensuse packages have been created for Scilab
5.0.3 and I applied most of their patches (or update some part of the
code) for Scilab 5.0.4.

= Redhat/Fedora =
The work is still going on:
https://bugzilla.redhat.com/show_bug.cgi?id=472639
They are also doing a great work packaging the misc dependencies but
they are a bit stuck about the JOGL packaging  (jogl and glugen should
