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.

Installation
You should create a directory for the downloaded files. Note that
you can compile your program using the following command:
%
% f77 source.f myprog.f
%
Please consult your system administrator for more information about
the Fortran compiler on your system.
See the
NSPCG User's Guide
for details on how to use the routines in the package.
