Given the stress tensor below, find the principal stresses

% based on a) the roots of the cubic characteristic polynomial and b)

using the

% eig command.

%

fprintf(' 3) principal stresses ')

% given code - the stress tensor

Sigma=[5 15 0;15 5 0;0 0 0]

% ******find the principal stresses using the eig command *******- leave off the ";" so

% your result will display in the command window

% *****compute the minors; determine the coefficients of the cubic polynomial;

and find the roots of the polynomial***** - leave off the ";" so all of your

result

% will display in the command window

please provide matlab code for the question
