Matlab library for SVM classification

Hello,

I started using Matlab SVM functions to classify geometrical shapes into 2 classes. I would now like to move on to >2 classes classification. I have been looking around for libraries and it seems that libsvm and svm-light might be good options. I am looking for a fast (of course...), flexible (for instance >2 classes), stable and easily Matlab interfaced library (possibly as easy as only having equivalents to svmtrain and svmclassify functions), any suggestions?

Best, Sébastien
