Problemi grafici con programmi scientifici

[LeoEdre]

Ho installato il kernel 2.6.33.6-desktop-nrj.69mib e gli ultimi driver nvidia sempre del MIB, ma ho problemi (mai avuti prima) con le funzioni grafiche di programmi scientifici come Matlab e Scilab. In sostanza, sembra che entrambi questi programmi non riescano ad usare OpenGL per disegnare i grafici, dando messaggi di errore che additano la colpa ai driver o addirittura crashando (è la prima volta in vita mia che vedo Matlab crashare).
Da premettere che non ritengo che questi problemi siano veramente imputabili al MIB, cioè potrebbe essere benissimo che si presentino anche con kernel e driver di Mandriva, solo che non mi è mai successo con nessuna versione precendente una cosa del genere.
I mesa-demos tra l'altro invece funzionano benissimo, così come gli effetti desktop e tutto il resto.

Well, I'm spanish and I don't understand right all your message.
I suppose you have your reasons to use Matlab versus Octave with Qtoctave.
Do you use Matlab with Linux version?
About Scilab i will test it, but Scilab is very easy to install it from official webpage.
Init Scilab from a terminal, and copy & paste here the error message when scilab crash.

Bye.

P.D. Please write me in English if it is possible

Scilab doesn't crash, but it can't plot anything. the error message is this:
-->plot(t, s)
Si consiglia di aggiornare i driver."
!--error 4
Undefined variable: mostra

I have used Matlab on Linux for years and I have never had a problem.

The problem is not nvidia, the problem is scilab pacakage from mandriva repo or java plot packages from mdv. While i've packed the new version you can use the new version.
Download the new version from http://www.scilab.org/products/scilab/d ... 3.0-beta-1

32 bits -> http://www.scilab.org/download/5.3.0-be ... 686.tar.gz

64 bits -> http://www.scilab.org/download/5.3.0-be ... _64.tar.gz

To use it:

Uncompress it in your home, for instance.
There is a /bin folder in the uncompressed new scilab folder. You'll see a file called scilab, execute it with left double click of your mouse. That's all.

I've tested it and it works fine.

Bye
You can make a launcher.

Yes, but what about Matlab? It has ALWAYS worked on linux and I have to use it for my engeneering courses.

[tobal]

Sorry, but I don't give support to none free software. I said yet before that exists Octave with Qtoctave as a free alternative to Matlab. I'm a mathematic and I use Octave, I never use Matlab.

Bye
