NAME
       TESTING/EIG/dlctes.f

SYNOPSIS
   Functions/Subroutines
       logical function dlctes (zr, zi, d)
           DLCTES

Function/Subroutine Documentation
   logical function dlctes (double precision zr, double precision zi, double
       precision d)
       DLCTES

       Purpose:


            DLCTES returns .TRUE. if the eigenvalue (ZR/D) + sqrt(-1)*(ZI/D)
            is to be selected (specifically, in this subroutine, if the real
            part of the eigenvalue is negative), and otherwise it returns
            .FALSE..

            It is used by the test routine DDRGES to test whether the driver
            routine DGGES successfully sorts eigenvalues.

       Parameters
           ZR

                     ZR is DOUBLE PRECISION
                     The numerator of the real part of a complex eigenvalue
                     (ZR/D) + i*(ZI/D).

           ZI

                     ZI is DOUBLE PRECISION
                     The numerator of the imaginary part of a complex eigenvalue
                     (ZR/D) + i*(ZI).

           D

                     D is DOUBLE PRECISION
                     The denominator part of a complex eigenvalue
                     (ZR/D) + i*(ZI/D).
