NAME
PDPTTRS - solve a system of linear equations A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)
SYNOPSIS
SUBROUTINE PDPTTRS(
N, NRHS, D, E, JA, DESCA, B, IB, DESCB, AF,
LAF, WORK, LWORK, INFO )
INTEGER
IB, INFO, JA, LAF, LWORK, N, NRHS
INTEGER
DESCA( * ), DESCB( * )
DOUBLE
PRECISION AF( * ), B( * ), D( * ), E( * ), WORK( * )
PURPOSE
PDPTTRS solves a system of linear equations
where A(1:N, JA:JA+N-1) is the matrix used to produce the factors
stored in A(1:N,JA:JA+N-1) and AF by PDPTTRF.
A(1:N, JA:JA+N-1) is an N-by-N real
tridiagonal symmetric positive definite distributed
matrix.

Routine PDPTTRF MUST be called first.
