Hi, I recently disovered that you could specify the type of the arguments of a function being defined. For exemple, f[x_Integer] if you want x to be an integer. There's also List, Real, Complex and Symbol. But there's also ?MatrixQ which is not in the Mathematica book, to specify a matrix. Are there other types?
