Generate the following MATLAB code:

1. (50 points) The first problem is about the iterative variant of the standard Gaussian elimination (GE). Answer the following questions and complete the Matlab code that uses iterative GE for image compression 1. Consider the matrix A A-1 4 2-1 2 Let A(0)- A. (a) Select the entry of A with the largest absolute value as a pvot A(0)(11?) (complete pivoting), i.e., in this case A(0) (2,3) = 4, i,-2 and ?= 3, and perform the following operation where A (o)(Lj) and A (0)(11.) denote column ji and row ? of Ao), respectively, and A(0) (11/1) is the pivot. (b) What is the rank of Matrix A(0)(ji)A0)G,: A(ij)? (c) What is the special structure of A We are done with the first iteration of GE after the operation (1)? 1.
