(ii) Write a Matlab / Octave program to determine the natural frequencies of vibration and their eigenvector. Compare the eigenvalue and eigenvectors with analytical method. Write a program in Matlab / Octave to execute a power method and inverse power method to determine the largest eigenvalue and smallest eigenvalue respectively with their Eigenpair. Discuss on your findings and observations for (iii) and (iv). Develop a Matlab/Octave program to plot the mode shapes vs time for two different initial conditions. Assuming length,l is 0.5m, g=9.81m's mass =2kg. Use initial condition (IC) [10°, 10°, 10°]" and another IC as in the study case.
