Fortran77 subroutines to solve large scale eigenvalue problems

Variants:
ARPACK software is capable of solving large scale symmetric, nonsymmetric, and generalized eigenproblems from significant application areas. The software is designed to compute a few (k) eigenvalues with user specified features such as those of largest real part or largest magnitude. Storage requirements are on the order of n*k locations. No auxiliary storage is required. A set of Schur basis vectors for the desired k-dimensional eigen-space is computed which is numerically orthogonal to working precision. Numerically accurate eigenvectors are available on request.

Important Features:

o Reverse Communication Interface. o Single and Double Precision Real Arithmetic Versions for Symmetric, Non-symmetric, o Standard or Generalized Problems. o Single and Double Precision Complex Arithmetic Versions for Standard or Generalized Problems. o Routines for Banded Matrices - Standard or Generalized Problems. o Routines for The Singular Value Decomposition. o Example driver routines that may be used as templates to implement numerous Shift-Invert strategies for all problem types, data types and precision.

1. Purpose 
   -------
   This directory contains example drivers that call subroutines
   [s,d]sband.f, [s,d]nband.f or [c,z]nband.f to solve various eigenvalue 
   problems in which matrices have BANDED structure. These drivers illustrate 
   how to construct LAPACK-style banded matrices, and how to set various 
   ARPACK parameters to solve different problems in different modes. The

1. Purpose 
   -------
   This directory contains example drivers that call ARPACK subroutines
