Part 2. Using numerical methods, calculate the maximum principal stress for the stress tensor characterised by following components: = Oxx = 0 MPa, Oyy = 1 MPa, Ozz = 5 MPa, Txy = 10 MPa, Txz = -3 MPa, tyz = 2 MPa. Create a MATLAB code which is capable of performing the following: Solving for the maximum principal stress value by using either (a) an original code employing one of the standard methods for solving eigenvalue problems, or (b) a built-in MATLAB eigenvalue solver. The solution should be obtained with the relative error of
