How to use msereg and cross-validation

I'm using a fitnet and i'd like to know if it's possible to do regularization, using msereg, and cross-validation at the same time. It seems that when i try it the regularized cost function is applied to the validation and test sets (using dividerand and divideind).

Yes, any cost function will be applied to the whole dataset.
