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. WebbThe power method is a numerical method for estimating the dominant eigenvalue and a corresponding eigenvector for a matrix. The inverse power method is the power method applied to the inverse of a matrix A. In general, the inverse power method converges to the smallest eigenvalue in absolute value of A.

The convergence rate of power method is determined by the ratio ρ = λ 1 / λ 2 ≥ 1, where λ 1 and λ 2 are the first and second largest eigenvalues (in magnitude). The larger the ratio is, the better convergece rate the iteration have.
