Suppose that A is an in m x n matrix, B is an n x p matrix, and C is a p x q matrix. The product ABC can be computed in two ways:

(a) First compute AB, and then multiply this (on the right) by C.

(b) First compute BC, and then multi 1 this on the left b A.

Use Exercise 49 to device a strategy that compares the two ways so that the more efficient one can be chosen.

Reference of exercise 49
