NAME

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

SYNOPSIS

SUBROUTINE PZDBSV( N, BWL, BWU, NRHS, A, JA, DESCA, B, IB, DESCB, WORK,
                   LWORK, INFO )
    INTEGER        BWL, BWU, IB, INFO, JA, LWORK, N, NRHS
    INTEGER        DESCA( * ), DESCB( * )
    COMPLEX*16     A( * ), B( * ), WORK( * )

PURPOSE

PZDBSV solves a system of linear equations

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

Gaussian elimination without pivoting
is used to factor a reordering
of the matrix into L U.
