Re: [Numpy-discussion] matrix multiplication (newbie question)

[Nadav H. <na...@vi...>]

Make A,B,... matrices instead of arrays, so instead

A =3D array((.....))

Write

A =3D matrix((....))

=20

Assuming you had

>From numpy import *

=20

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=3DB*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
