salut à tous,
bon je saute sur l'occasion pour poser la question sur les mex files.
en fait j'ai des programmes en C je les exécutés sous matlab, mais quand je les ai modifiés et relancés ca m'a posé un problème au niveau de l'éxécution de mex.
à votre avis ou se situe le problème?? je suis vraiment bloquée et je n'arrive pas à modifier les programmes C pour avancer.:(
Sans les messages d'erreur ou plus d'informations, ce sera très difficile de te répondre :?
bonjour Dut;Citation:

à partir de l'excusion des programmes C sous matlab voila ce qu'il m'affiche, j'ai dû comprendre que je suis en train de violer l'utilisation du programme, parceque je l'ai récupéré, pourtant l'auteur a donné sa permission de l'utiliser et il a donné meme ce qu'il faut faire pour pouvoir le modifier ??? mais ca marche pas

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.
If it is an official MathWorks function, please
follow these steps in reporting this problem to The MathWorks so
that we have the best chance of correcting it:
1. Send this crash report to segv@mathworks.com for automated analysis.
For your convenience, this information has been recorded in:
C:\DOCUME~1\WINDOWS\LOCALS~1\Temp\matlab_crash_dump.1432
2. Also, if the problem is reproducible, send the crash report to
support@mathworks.com along with:
- A specific list of steps that will reproduce the problem
- Any M, MEX, MDL or other files required to reproduce the problem
- Any error messages displayed to the command window
A technical support engineer will contact you with further information.
Thank you for your assistance. Please save your workspace and restart
MATLAB before continuing your work.
==============================================================
en quelle version cette dll fonctionnait tu le sait?
Là d'apres le crash on voit que tu l'utilises en R14.
Il se peut qu'il faille la recompiler si elle a été faite en R13 par exemple.
aparament c'est ca. mais avant d'exécuter j'ai recompilé les programmes suivant les indications de l'auteur :?Citation:
