SYNOPSIS

SUBROUTINE PSPBSV(

UPLO, N, BW, NRHS, A, JA, DESCA, B, IB, DESCB, WORK, LWORK, INFO )

CHARACTER

UPLO

INTEGER

BW, IB, INFO, JA, LWORK, N, NRHS

INTEGER

DESCA( * ), DESCB( * )

REAL

A( * ), B( * ), WORK( * )

PURPOSE

PSPBSV solves a system of linear equations

where A(1:N, JA:JA+N-1) is an N-by-N real

banded symmetric positive definite distributed

matrix with bandwidth BW.

Cholesky factorization is used to factor a reordering of

the matrix into L L'.
