Question

Writing a Matlab function file find the eigenvalues and the corresponding eigenvectors of the matrix B = [4 3 7; 1 2 6; 2 0 4].  

Answer 1

The Matlab function file is given below:

function eigenfun = eigen( B )
%UNTITLED Summary of this function goes here
% Detailed explanation goes here
[V,D]=eig(B);
S='The Eigenvalues are :';
disp(S)
D
S='The Eigenvectors are :';
disp(S)
V

end

The main script file is given below:

B=[4 3 7;1 2 6;2 0 4];
eigen(B)

The screenshot with output is given below:
