How do I partition data sets for cross validation in MATLAB?

I'm trying to split, or partition, the data into two groups. Testing Data and Training Data. Ideally I want to write a function that can randomly divide the data into a variable sized patition. So that I could do specifi and leave one out cross validation. I'm not sure how I'll do this though.

Hi

It is my understanding that you want to partition the dats randomly. You can use either cvpartition from Statistics and Machine Learning Toolbox or randperm to serve the purpose.

The following answer might help you to understand how to use 'randperm'
