PZDTSV(l)						   LAPACK routine (version 1.5) 						 PZDTSV(l)

NAME
       PZDTSV - solve a system of linear equations   A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)

SYNOPSIS
       SUBROUTINE PZDTSV( N, NRHS, DL, D, DU, JA, DESCA, B, IB, DESCB, WORK, LWORK, INFO )

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

	   INTEGER	  DESCA( * ), DESCB( * )

	   COMPLEX*16	  B( * ), D( * ), DL( * ), DU( * ), WORK( * )

PURPOSE
       PZDTSV solves a system of linear equations

       where A(1:N, JA:JA+N-1) is an N-by-N complex
       tridiagonal diagonally dominant-like distributed
       matrix.

       Gaussian elimination without pivoting
       is used to factor a reordering
       of the matrix into L U.

       See PZDTTRF and PZDTTRS for details.
