> This problem is nagging me as well. I can only get this to work if I turn off the pre and post processing entirely. I've tried adding mapminmax() to my own feedforward calculation, but I was not able to replicate MATLAB's calculations. I would love to know. I need the hidden node values, and the only way to get those is to do so manually--ie no built in method in the net object. And, as a sanity check, it would be nice if I could match
>predictions with the processing functions turned on.


Don't forget that targets are also normalized for training.

Therefore outputs have to be unnormalized in order to get the final answer.
