[im]: 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.
[im] All I could find was the numeric function 'matrix_multiply, but this only takes two arguments.
Have a look at the examples "dot()" and "mat()" in the Numpy Example List.
