Linear system

Objective: Main Script: clc clear all close all % Coefficient matrix A=[5 1 2;-3 9 4;1 2 -7]; %n=length(A); %RHS B=[10;-14;33]; %diagonal matrix D=diag(diag(A)); %lower diagonal matrix L=tril(A)-D ; %Upper diaginal matrix U=triu(A)-D ; %Effect of changing the diagonal element E=0.1:0.1:1; for i=1:length(E) D=E(i)*D %Calculating iteration…
