Detailed Description

template<class Scalar>
class RVLUmin::PowerStep< Scalar >

This Algorithm does a single iteration of the Power Method for estimating the largest singular value of a linear operator.

It also estimates the relative residual |lam -rq|/|lam|, in which lam is the eigenvalue of the normal operator which the Rayleigh quotient rq approximates.
