Then I thought, what if I replace the (*) and (+) operations which are applied when I multipy the matrix with a vector (i.e. a vector if inputs or outputs) by something more general. So I replaced (+) by function application and my matrix was now a matrix of functions. But then I got lost trying to find a way to invert such a matrix.
You'd have to have a general way of finding the inverse of a function, which doesn't exist (many functions aren't invertible at all, for example). -Steve
