You need to show us the exact error message indicating which line the problem is occurring on.

fix trainingF size
trainingF = zeros(size(training,2)*training(1).Count,size(feature,2));

How can I solve this error?
Error:
Subscripted assignment dimension mismatch
trainingL{featurecount}=training(i):Description;
Thanks

The : operator is a range construction operator, and is unlikely to be correct in this context.
