PSDBTRS(l) LAPACK routine (version 1.5) PSDBTRS(l)NAMEPSDBTRS - solve a system of linear equations A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)SYNOPSISSUBROUTINE PSDBTRS( TRANS, N, BWL, BWU, NRHS, A, JA, DESCA, B, IB, DESCB, AF, LAF, WORK, LWORK, INFO ) CHARACTER TRANS INTEGER BWL, BWU, IB, INFO, JA, LAF, LWORK, N, NRHS INTEGER DESCA( * ), DESCB( * ) REAL A( * ), AF( * ), B( * ), WORK( * )PURPOSEPSDBTRS 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 PSDBTRF. A(1:N, JA:JA+N-1) is an N-by-N real banded diagonally dominant-like distributed matrix with bandwidth BWL, BWU. Routine PSDBTRF MUST be called first. LAPACK version 1.5 12 May 1997 PSDBTRS(l)
