SYNOPSIS

SUBROUTINE PDPBSV(

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( * )

    

DOUBLE PRECISION A( * ), B( * ), WORK( * )

PURPOSE

PDPBSV solves a system of linear equations

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

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