3.6. Let A be a real matrix of size m xn. 1. What condition should A meet for the function 2 ||Ax ||, where ||.|| denotes some norm on R", to be a norm on R? Write a function NormA that computes || A.c||2 for x ER". 2. Assume A is a square matrix. Write a function NormAs that computes (Ax, x) for x ER". Does this function define a norm on R? 3.6.
