NAME
       TESTING/EIG/slctes.f

SYNOPSIS
   Functions/Subroutines
       logical function slctes (zr, zi, d)
           SLCTES

Function/Subroutine Documentation
   logical function slctes (real zr, real zi, real d)
       SLCTES

       Purpose:


            SLCTES 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 SDRGES to test whether the driver
            routine SGGES successfully sorts eigenvalues.

       Parameters
           ZR

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

           ZI

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

           D

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