PDGBTRS(l)						   LAPACK routine (version 1.5) 						PDGBTRS(l)

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

SYNOPSIS
       SUBROUTINE PDGBTRS( TRANS, N, BWL, BWU, NRHS, A, JA, DESCA, IPIV, B, IB, DESCB, AF, LAF, WORK, LWORK, INFO )

	   CHARACTER	   TRANS

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

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

	   DOUBLE	   PRECISION A( * ), AF( * ), B( * ), WORK( * )

PURPOSE
       PDGBTRS solves a system of linear equations
					 or
		 A(1:N, JA:JA+N-1)' * X = B(IB:IB+N-1, 1:NRHS)

       where A(1:N, JA:JA+N-1) is the matrix used to produce the factors stored in A(1:N,JA:JA+N-1) and AF by PDGBTRF.
       A(1:N, JA:JA+N-1) is an N-by-N real
       banded distributed
       matrix with bandwidth BWL, BWU.

       Routine PDGBTRF MUST be called first.
