1. Show that matrix multiplication can be implemented using tensor products as defined in Problem 9.5, and write an algorithm that does it.

2. What is the action of the following algorithm? Determine its flop count.

Hint: To help determine its action, trace the algorithm using
 matrices. These formulas are useful when determining the flop count:
