ARPACK-NG is a collection of Fortran77 subroutines designed to solve large scale eigenvalue problems.
|
|
|
|
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.
|
|
|
|
This project is a joint project between Debian, Octave and Scilab in order to
|
|
provide a common and maintained version of arpack.
|
|
|
|
Indeed, no single release has been published by Rice university for the last
|
|
few years and since many software (Octave, Scilab, R, Matlab...) forked it and
|
|
implemented their own modifications, arpack-ng aims to tackle this by providing
|
|
a common repository and maintained versions.
|
|
|
|
arpack-ng is replacing arpack almost everywhere.
