Summary A collection of Fortran77 subroutines designed to solve large scale eigenvalue problems
Description Important Features: * Reverse Communication Interface. * Single and Double Precision Real Arithmetic Versions for Symmetric, Non-symmetric, Standard or Generalized Problems. * Single and Double Precision Complex Arithmetic Versions for Standard or Generalized Problems. * Routines for Banded Matrices - Standard or Generalized Problems. * Routines for The Singular Value Decomposition. * Example driver routines that may be used as templates to implement numerous Shift-Invert strategies for all problem types, data types and precision.
