Make A,B,... matrices instead of arrays, so instead
A = array((.....))
Write
A = matrix((....))
Assuming you had

Subject: [Numpy-discussion] matrix multiplication (newbie question)
Hi
Sorry if this is an obvious question, but what is the easiest way to
multiply matrices in numpy? Suppose I want to do A=B*C*D. The ' * '
operator apparently does element wise multiplication, as does the
'multiply' ufunc. All I could find was the numeric function
'matrix_multiply, but this only takes two arguments.
Thanks in advance!
Izak
