Question

Please type out Matlab code

Answer 1

MATLAB Code:

close all
clear
clc

A = [2 -1 0; -1 2 -1; 0 -1 2];
eig_vals = eig(A); % Get the Eigen values
sum_eig_vals = sum(eig_vals); % Sum of Eigen values
tr = trace(A);
if tr == sum_eig_vals
disp('Trace = Sum of Eigen values.')
else
disp('Trace is not equal to sum of Eigen values.')
end

Output:

Trace = Sum of Eigen values.
