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?
