PDPTSV(l) ) PDPTSV(l)NAME
PDPTSV - solve a system of linear equations A(1:N, JA:JA+N-1) * X =
B(IB:IB+N-1, 1:NRHS)
SYNOPSIS
SUBROUTINE PDPTSV( N, NRHS, D, E, JA, DESCA, B, IB, DESCB, WORK, LWORK,
INFO )
INTEGER IB, INFO, JA, LWORK, N, NRHS
INTEGER DESCA( * ), DESCB( * )
DOUBLE PRECISION B( * ), D( * ), E( * ), WORK( * )
PURPOSE
PDPTSV solves a system of linear equations A(1:N, JA:JA+N-1) * X =
B(IB:IB+N-1, 1:NRHS) where A(1:N, JA:JA+N-1) is an N-by-N real
tridiagonal symmetric positive definite distributed
matrix.
Cholesky factorization is used to factor a reordering of
the matrix into L L'.
