Computing eigenvalues: Lanczos algorithm with a new recursive partitioning method
The Lanczos algorithm with a new recursive partitioning method to compute the eigenvalues, in a given specified interval, is presented in this paper. Comparisons have been made respecting the numerical results as well as the CPU-time with that of the Sturm sequence-bisection method. (C) 1999 Elsevier Science Ltd. All rights reserved.
