PDDBTRS(l) | LAPACK routine (version 1.5) | PDDBTRS(l) |
NAME¶
PDDBTRS - solve a system of linear equations A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)SYNOPSIS¶
- SUBROUTINE PDDBTRS(
- TRANS, N, BWL, BWU, NRHS, A, JA, DESCA, B, IB, DESCB, AF, LAF, WORK, LWORK, INFO )
PURPOSE¶
PDDBTRS 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 PDDBTRF.
A(1:N, JA:JA+N-1) is an N-by-N real
banded diagonally dominant-like distributed
matrix with bandwidth BWL, BWU.
Routine PDDBTRF MUST be called first.
