The Power Method is a classic numerical algorithm for determining the largest eigenvalue and eigenvector
associated with a matrix A. Write a matlab function that returns the largest eigenvalue and eigenvector
using the Power Method (see wikipedia) for a given matrix A. Construct the algorithm so that it always
runs 100 iterations – you should not implement a stopping criteria. Do not copy others codes. Test
your algorithm on the matrix: A = [2.0, 0.2, 1.0; 0.2, 4.0, 1.3; 0.0, 1.3, 3.0] using an initial eigenvector
guess of b = [1; 1; 1].
