NSPCG Software Package

NSPCG was developed at the Center for Numerical Analysis, the University of Texas at Austin, by Thomas Oppe, Wayne Joubert, David Kincaid, and David Young. It is a collection of Fortran subroutines for solving large sparse linear systems by adaptive accelerated iterative algorithms.

Please send email to Dr. David R. Kincaid if you have any questions about NSPCG.
