PSGBSV(l) | LAPACK routine (version 1.5) | PSGBSV(l) |
NAME¶
PSGBSV - solve a system of linear equations A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)SYNOPSIS¶
- SUBROUTINE PSGBSV(
- N, BWL, BWU, NRHS, A, JA, DESCA, IPIV, B, IB, DESCB, WORK, LWORK, INFO )
PURPOSE¶
PSGBSV solves a system of linear equationswhere A(1:N, JA:JA+N-1) is an N-by-N real
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 PSGBTRF and PSGBTRS for details.
