Power method (von Mises) for eigenvalue computations.
This method determines the largest eigenvalue of a matrix by applying increasing powers of this matrix to a vector. If there is an eigenvalue with dominant absolute value, the iteration vectors will become aligned to its eigenspace and
.
A shift parameter allows to shift the spectrum, so it is possible to compute the smallest eigenvalue, too.
Convergence of this method is known to be slow.
