PDPTTRS(l)						   LAPACK routine (version 1.5) 						PDPTTRS(l)

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.
