摘要: Recently developed minimization methods are applied to the of Rayleigh quotient a general eigensystem, producing efficient iterative for finding extremal eigenvalues and associated eigenvectors. Numerical results quoted systems widely differing order, an assessment is made, together with how they compare against other well-known methods.
