PSPBSV(l)						   LAPACK routine (version 1.5) 						 PSPBSV(l)

NAME
       PSPBSV - solve a system of linear equations   A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)

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'.

       See PSPBTRF and PSPBTRS for details.
