B(IB:IB+N-1, 1:NRHS)
SYNOPSIS
SUBROUTINE PZPTSV( UPLO, N, NRHS, D, E, JA, DESCA, B, IB, DESCB, WORK,
LWORK, INFO )
CHARACTER UPLO
INTEGER IB, INFO, JA, LWORK, N, NRHS
INTEGER DESCA( * ), DESCB( * )
COMPLEX*16 B( * ), E( * ), WORK( * )
DOUBLE PRECISION D( * )
PURPOSE
PZPTSV 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 complex
tridiagonal symmetric positive definite distributed
matrix.
Cholesky factorization is used to factor a reordering of
the matrix into L L'.
