SYNOPSIS
 SUBROUTINE PCDTSV(

N, NRHS, DL, D, DU, JA, DESCA, B, IB, DESCB,
WORK, LWORK, INFO )

INTEGER
IB, INFO, JA, LWORK, N, NRHS

INTEGER
DESCA( * ), DESCB( * )

COMPLEX
B( * ), D( * ), DL( * ), DU( * ), WORK( * )
PURPOSE
PCDTSV solves a system of linear equations
where A(1:N, JA:JA+N1) is an NbyN complex
tridiagonal diagonally dominantlike distributed
matrix.
Gaussian elimination without pivoting
is used to factor a reordering
of the matrix into L U.
See PCDTTRF and PCDTTRS for details.
