Nouveau problème.
Mon fichier C compile bien, mais lors de l'appel de la fonction dans mon programme Matlab, ça ne marche pas du tout.
J'ai mis ce qu'il m'écrit ci-après.
J'utilise dans mon programme C des fonctions qui ne sont pas des Mex-Functions (par exemple la fonction exp). L'erreur viendrait-elle d'ici?

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: /****/******/matlab_crash_dump.16523 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. Error in ==> classifSVM at 90 [A, B] = sigmoidSVM(Ysig, Ytr);
