NAME
PSGBSV  solve a system of linear equations A(1:N, JA:JA+N1) * X = B(IB:IB+N1, 1:NRHS)
SYNOPSIS
 SUBROUTINE PSGBSV(

N, BWL, BWU, NRHS, A, JA, DESCA, IPIV, B, IB,
DESCB, WORK, LWORK, INFO )

INTEGER
BWL, BWU, IB, INFO, JA, LWORK, N, NRHS

INTEGER
DESCA( * ), DESCB( * ), IPIV( * )

REAL
A( * ), B( * ), WORK( * )
PURPOSE
PSGBSV solves a system of linear equations
where A(1:N, JA:JA+N1) is an NbyN real
banded distributed
matrix with bandwidth BWL, BWU.
Gaussian elimination with pivoting
is used to factor a reordering
of the matrix into P L U.
See PSGBTRF and PSGBTRS for details.
