Programming 1. (a) Write a function that takes as input - dimension n; n n matrix A; and calculates the LU factorization of A, stored in a single matrix overwriting A, and outputs the number of flops used. Write out or print out your function and turn it i (b) Run the case with on n n matrices with value n on the diagonal and-1 for all other elements, for n 25,50, 100, 200. Write out or print out your results
