Using the outer product you get a matrix that has the right size and contents but it is m*n by p*q Was that a misprint in your post?
x array([1, 2, 3, 4, 5, 6]) x.shape=(3,2) y = 10*transpose(x) y array([[10, 30, 50], [20, 40, 60]]) z = outerproduct(x.flat, y.flat) z array([[ 10, 30, 50, 20, 40, 60], [ 20, 60, 100, 40, 80, 120], [ 30, 90, 150, 60, 120, 180], [ 40, 120, 200, 80, 160, 240], [ 50, 150, 250, 100, 200, 300], [ 60, 180, 300, 120, 240, 360]])

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.
