NAME

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

SYNOPSIS

SUBROUTINE PCDBTRS(

TRANS, N, BWL, BWU, NRHS, A, JA, DESCA, B, IB,
DESCB, AF, LAF, WORK, LWORK, INFO )

CHARACTER
TRANS

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

INTEGER
DESCA( * ), DESCB( * )

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

PURPOSE

PCDBTRS 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 PCDBTRF.
A(1:N, JA:JA+N-1) is an N-by-N complex
banded diagonally dominant-like distributed
matrix with bandwidth BWL, BWU.
