Annotation
Lanczos-type methods are applied for solving the generalized algebraic eigenvalue problem which occurs in the finite-element waveguide mode analysis. The line of approach is suggested, which stabilizes the calculation of smaller eigen- values in the presence of a high-multiplicity zero eigenvalue. Computational features of the problem are discussed.
