SYNOPSIS

SUBROUTINE PZGBSV(

N, BWL, BWU, NRHS, A, JA, DESCA, IPIV, B, IB, DESCB, WORK, LWORK, INFO )

INTEGER

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

INTEGER

DESCA( * ), DESCB( * ), IPIV( * )

COMPLEX*16

A( * ), B( * ), WORK( * )

PURPOSE

PZGBSV solves a system of linear equations

where A(1:N, JA:JA+N-1) is an N-by-N complex

banded distributed

matrix with bandwidth BWL, BWU.

Gaussian elimination with pivoting

is used to factor a reordering

of the matrix into P L U.
