Hello,
Can anyone please explain the difference between usage of crossval and crossvalind function? I understand that both are used for cross validation. But I'm confused which one to use. Will both produce same result?
Thanks, Rohit

crossvalind generates the indices that you can use for a general K-fold cross validation and enables you to select the training and test data
crossval actually preforms a 10-fold cross validation where you input a function handle

Can you please provide a basic example code of crossval with svm? I have overall values of 7 features for 50 entries.
Also at present I'm trying to work it out with the code http://pastebin.com/sTRSy2q4. Is this the right way? I mean this tells me the final performance of my classifier, or do I need to do any more steps?
