Thanks, if the input is in the form of matrices, what other "functions" can be used?

Unfortunately there is no easy deterministic way of training intelligence into a response function for a given input. The other technique that is commonly used is Fuzzy Logic but without knowing the details of your problem I have no idea if it will work for you.
What ever technique you use will require skill on your part in its use. If you where to post some details of your problem I might be able to make better suggestions. It might well be that Neural Networks are the way to go and you have a design or training problem,
I am assuming you are using back propagation for training if you have a forward -feeding network or do you have a feedback network?
