NAME

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

SYNOPSIS

       SUBROUTINE PSDTTRS( 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( * )

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

PURPOSE

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

       Routine PSDTTRF MUST be called first.
