I would appreciate it, if Numpy could handle the Kronecker-product of
two matrices X, Y.

kron(X,Y) is the Kronecker tensor product of X and Y.
The result is a large matrix formed by taking all possible products
between the elements of X and those of Y. If X is m-by-n
and Y is p-by-q, then kron(X,Y) is m*p-by-n*q.
