The general utility of a discretized variable basis for the internal rotor eigenvalue problem, especially when coupled with an algebraic determinantal approach, is demonstrated. The computational routines are simple recursive ones and the incorporation of symmetry constraints is straightforward. The
A new iterative method based on a Newton correction vector for extension of the Krylov subspace, its diagonal, and band versions are proposed for calculation of selected lowest eigenvalues and corresponding eigenvectors of the generalized symmetric eigenvalue problem. Additionally, diagonal and band
