PZPBSV(l) LAPACK routine (version 1.5) PZPBSV(l)

NAME

PZPBSV - solve a system of linear equations A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)

SYNOPSIS

SUBROUTINE PZPBSV(
UPLO, N, BW, NRHS, A, JA, DESCA, B, IB, DESCB, WORK, LWORK, INFO )
CHARACTER UPLO INTEGER BW, IB, INFO, JA, LWORK, N, NRHS INTEGER DESCA( * ), DESCB( * ) COMPLEX*16 A( * ), B( * ), WORK( * )

PURPOSE

PZPBSV solves a system of linear equations

where A(1:N, JA:JA+N-1) is an N-by-N complex
banded symmetric positive definite distributed
matrix with bandwidth BW.

Cholesky factorization is used to factor a reordering of
the matrix into L L'.

See PZPBTRF and PZPBTRS for details.
