PZPBTRS(l)						   LAPACK routine (version 1.5) 						PZPBTRS(l)

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

SYNOPSIS
       SUBROUTINE PZPBTRS( UPLO, N, BW, NRHS, A, JA, DESCA, B, IB, DESCB, AF, LAF, WORK, LWORK, INFO )

	   CHARACTER	   UPLO

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

	   INTEGER	   DESCA( * ), DESCB( * )

	   COMPLEX*16	   A( * ), AF( * ), B( * ), WORK( * )

PURPOSE
       PZPBTRS solves a system of linear equations

       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 PZPBTRF.
       A(1:N, JA:JA+N-1) is an N-by-N complex
       banded symmetric positive definite distributed
       matrix with bandwidth BW.
       Depending on the value of UPLO, A stores either U or L in the equn A(1:N, JA:JA+N-1) = U'*U or L*L' as computed by PZPBTRF.

       Routine PZPBTRF MUST be called first.
