PCGBTRS(l) LAPACK routine (version 1.5) PCGBTRS(l)NAMEPCGBTRS - solve a system of linear equations A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)SYNOPSISSUBROUTINE PCGBTRS( 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(*) COMPLEX A( * ), AF( * ), B( * ), WORK( * )PURPOSEPCGBTRS 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 PCGBTRF. A(1:N, JA:JA+N-1) is an N-by-N complex banded distributed matrix with bandwidth BWL, BWU. Routine PCGBTRF MUST be called first. LAPACK version 1.5 12 May 1997 PCGBTRS(l)
