PCGBSV(l)						   LAPACK routine (version 1.5) 						 PCGBSV(l)

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

SYNOPSIS
       SUBROUTINE PCGBSV( 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	  A( * ), B( * ), WORK( * )

PURPOSE
       PCGBSV 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.

       See PCGBTRF and PCGBTRS for details.
