NAME¶
PZDBSV - solve a system of linear equations A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)SYNOPSIS¶
- SUBROUTINE PZDBSV(
- N, BWL, BWU, NRHS, A, JA, DESCA, B, IB, DESCB, WORK, LWORK, INFO )
PURPOSE¶
PZDBSV solves a system of linear equationswhere A(1:N, JA:JA+N-1) is an N-by-N complex
banded diagonally dominant-like distributed
matrix with bandwidth BWL, BWU.
Gaussian elimination without pivoting
is used to factor a reordering
of the matrix into L U.
See PZDBTRF and PZDBTRS for details.
