First recall that a step of Rayleigh quotient iteration (RQI) for the standard eigenproblem Ax = [lambda]x is to solve ii from (A - [theta]I)[?
As the computation of roots of polynomials is in general very sensitive to small perturbations in the coefficients, one might want to use Rayleigh quotient iteration in order to improve the accuracy of the computed eigenvalues.
