title: Input of Neural Network is a matrix
body: <p>i need a neural network where i can put 10 inputs: the first 9 are simple numbers, the last one is a Matrix (15x15). My outputs will be the last 3 numbers. There is any way to do it without transforming the matrix into a vector? Becouse if i'll transform it in a vector i'll loose the position of my numbers, or not?
  Thank you very much.</p>
