pzdbtrs(3)

NAME

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

SYNOPSIS

SUBROUTINE PZDBTRS( 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*16      A( * ), AF( * ), B( * ), WORK( * )

PURPOSE

PZDBTRS 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 PZDBTRF.
A(1:N, JA:JA+N-1) is an N-by-N complex
banded diagonally dominant-like distributed
matrix with bandwidth BWL, BWU.
Routine PZDBTRF MUST be called first.
