Webb9 maj 2012 · The power iteration method requires that you repeatedly multiply a candidate eigenvector, v, by the matrix and then renormalize the image to have unit norm. If you repeat this process many times, the iterates approach the largest eigendirection for almost every choice of the vector v. You can use that fact to find the eigenvalue and eigenvector.
