This is quite a broad topic, and it helps to have both some theoretical understanding of the mechanisms and a reasonably good idea of what it is you are trying to achieve (and some patience with the neural net learning process). That said, Brian Schott has put together an example and a lab (which I see he has mentioned while I was composing this message).
That said, there are other options which might or might not be better for whatever it is you are specifically trying to do (including genetic searches - not to be confused with biological genetics, linear algebra, hill climbing and so on...). https://en.wikipedia.org/wiki/Genetic_algorithm http://www.wikihow.com/Divide-Matrices (note that the first sentence there is false. J for example represents matrix division using %. and the process is faster than finding the matrix inverse).
