svmtrain function in matlab never exits ... do alternatives exist?

I am trying to learn how to use support vector machines in matlab. I have the bioinformatics toolbox, which has SVM functions svmtrain and svmclassify.

I managed to successfully use it for some reference data sets, with some nice accuracy. When I try to use the svm on my actual data the training never stops. My data set is 400 instances in 25 dimensions, so it should not take very long?!

Can I use other solvers in matlab? I dont want to buy new toolbox please ...

There are several things that may cause problems for training, but it should not run infinitely. Do you get any errors when using the solver?

With regard to alternatives: LIBSVM has an interface to . This is a state-of-the-art library with thousands of users. I highly recommend it, because it is easy to install/use and offers additional functionality for parameter tuning and more.
