NAME

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

SYNOPSIS

       SUBROUTINE PZGBTRS( 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(*)

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

PURPOSE

       PZGBTRS 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 PZGBTRF.
       A(1:N, JA:JA+N-1) is an N-by-N complex
       banded distributed
       matrix with bandwidth BWL, BWU.

       Routine PZGBTRF MUST be called first.
