SYNOPSIS

SUBROUTINE PCDTTRS(

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

    

CHARACTER TRANS

    

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

    

INTEGER DESCA( * ), DESCB( * )

    

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

PURPOSE

PCDTTRS solves a system of linear equations
                                  or

          A(1:N, JA:JA+N-1)' * X = B(IB:IB+N-1, 1:NRHS)

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

Routine PCDTTRF MUST be called first.
