PLEASE DO NOT PUT THE SAME ANSWER BEFORE I POSTED IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

We will make function file as function [U.cl=GEpp(A,b) on MATLAB. pp=partial pivoting function (U.cl=GEpp(A,b) n=length(b) for k=1: n-1 1. Loop will be here: 'determiner in la ment = maxksisn la If abs(A(r,k))> A= >>b= >> U.cl=GEpp(A,b) Example: A= [1 -1 2-1 -8 2-2 3-3 -20 1110 -2 1-1 434] Gauss elimination steps: 1) R2_R2-1/2R1 R3 R3-1/2R1 R4_R4-1/2R1 2) Swap R2_R3 3) Swap R3_R4 4) R4_R4-1/5R3 Ux=C X=(-7,3,2,2]T
