1. Recall that matrix A = = (aij) is called upper Hessenberg if aij you use Gauss elimination to solve Ax b with A being upper Hessenberg and suppose you do not need to swap rows. How many flops (floating point operations) are needed? You only need to consider the number of multiplications/divisions. Present your answer by big O notation. [5 marks] = = 0 when i > j+1. Suppose
