PSGBTRS(l)						   LAPACK routine (version 1.5) 						PSGBTRS(l)

NAME
PSGBTRS - solve a system of linear equations A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)
SYNOPSIS
SUBROUTINE PSGBTRS( TRANS, N, BWL, BWU, NRHS, A, JA, DESCA, IPIV, B, IB, DESCB, AF, LAF, WORK, LWORK, INFO ) CHARACTER TRANS INTEGER BWU, BWL, IB, INFO, JA, LAF, LWORK, N, NRHS INTEGER DESCA( * ), DESCB( * ), IPIV(*) REAL A( * ), AF( * ), B( * ), WORK( * )
PURPOSE
PSGBTRS 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 PSGBTRF. A(1:N, JA:JA+N-1) is an N-by-N real banded distributed matrix with bandwidth BWL, BWU. Routine PSGBTRF MUST be called first. LAPACK version 1.5 12 May 1997 PSGBTRS(l)
