You may have a look at http://scipy.org/Cookbook/MultiDot
Several alternatives are proposed.

Hi,
Suppose I have an array of shape: (n, k, k). In this case, I have n
k-by-k matrices. My goal is to compute the product of a (potentially
large) user-specified selection (with replacement) of these matrices.
For example,
x = [0,1,2,1,3,3,2,1,3,2,1,5,3,2,3,5,2,5,3,2,1,3,5,6]
says that I
