NAME

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

SYNOPSIS

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

           CHARACTER        TRANS, UPLO

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

           INTEGER          DESCA( * ), DESCB( * )

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

PURPOSE

       PDPBTRSV solves a banded triangular system of linear equations
                                      or
                           A(1:N, JA:JA+N-1)^T * X = B(IB:IB+N-1, 1:NRHS)

       where A(1:N, JA:JA+N-1) is a banded
       triangular matrix factor produced by the
       Cholesky factorization code PDPBTRF
       and is stored in A(1:N,JA:JA+N-1) and AF.
       The matrix stored in A(1:N, JA:JA+N-1) is either
       upper or lower triangular according to UPLO,
       and the choice of solving A(1:N, JA:JA+N-1) or A(1:N, JA:JA+N-1)^T is dictated by the user
       by the parameter TRANS.

       Routine PDPBTRF MUST be called first.
