arpack2-dev
- Fortran77 subroutines to solve large scale eigenvalue problems.
/Main/Debian/ia64/math/
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.
