Math Forum / Math Software / Scilab / November 2008

First off, I'm using Mac OS X Version 10.5.5.  I have installed
Scilab-4.1.2 which seems to the latest non-Gtk available for Mac.
Everything seems to be working properly except copy&paste in scipad or
in scilab.

Its not clear whether the frequency entry for the sinusoidal generator
in scicos is to be given in Hertz or in radian per second. I was
assuming this is in Hertz, and had to debug for sometime to realize
that this needs to be given in radian per second.

I am new to Scilab.  I have used Matlab at school and I want to use a
free version and similar application at home, and I read that Scilab
is a good choice.  Recently I want to do some research on Lego NXT and
I know that there is a NXT toolbox for Matlab:

Has anyone experienced problems with version 5.0.3 (or 5.0.anything)
crashing the Java virtual machine?  I've got 5.0.3 installed on two
laptops with Ubuntu 8.04, and both of them fail to display graphics; on
one of them I caught the JVM in the act of spewing out a yard-long file ...

When I invoke scicos the scilab prompt hangs till I exit the scicos
application.
In scicos, I want to give some variable names as values to blocks
( say frequency of a sinusoid generator), and want to set them through

Hy !
How to sort value from a amtrix  with a test on a specific column ?
example : I want x without all row with a firt value as big as 2.
-->x

I am wondering whether the Thermo_net3 package is supposed to work in
scilab-5.0.3.
I get the following error message when running the simple 'TestPipe1'
scicos file:

Hi Forum,
if i open a file in Scipad (Version 5.0.1 or 5.0.3) and want
to load it into the Scilab command line then nothing
happens. Scilab is installed on Windows XP.

Has anyone successfully been able to run the examples for calling
Scilab from within C code on WinXP?  I've just upgraded to v5.0.3 and
am trying to get at least one of the examples under the call_scilab
tree to work.  I am working with National Instruments LabWindows CVI

I'm using scilab-5.0.3 (binary version) under Windows XP. Can anybody
tell me how to enable printing from scilab's console ? (I have the
same problem with Scipad.) I tried the print button and e.g.
toprint(SCI+"/etc/scilab.start").

To perform some optics experiment, I want to display and print some
two-dimensionnal periodic figure (like a periodic paperwall) using only
black or white colours. So, I have wrote a program using Sfgrayplot
function, that repeats the same elementary figure in N rows and N

how can I add new fields to a struct and name it during runtime?
I read the information from a file and want to add a new field for
each pair of data. My problem is that the fieldname is also listed in
file.

Hello, everyone.
My scilab environment is,
version: scilab 4.1.2
OS :  Mac OS 10.5.5(Intel Mac)

I'm experiencing some problems with Scicos under Scilab 5.0.x for WXP
SP3.
- Pal Tree command is not working. The new window appears with the
blocks name but without icons. When I try to drag the block's name

Can someone tell me why this program doesn't work?  The first part prints
the function just fine but when I take the comments off the "plot3d"
statement I get an "inconsisttne addition error (error 8).  I may be
going at this all wrong but I'm new to scilab  . . . .
