NAME
       TESTING/EIG/cslect.f

SYNOPSIS
   Functions/Subroutines
       logical function cslect (z)
           CSLECT

Function/Subroutine Documentation
   logical function cslect (complex z)
       CSLECT

       Purpose:


            CSLECT returns .TRUE. if the eigenvalue Z is to be selected,
            otherwise it returns .FALSE.
            It is used by CCHK41 to test if CGEES successfully sorts eigenvalues,
            and by CCHK43 to test if CGEESX successfully sorts eigenvalues.

            The common block /SSLCT/ controls how eigenvalues are selected.
            If SELOPT = 0, then CSLECT return .TRUE. when real(Z) is less than
            zero, and .FALSE. otherwise.
            If SELOPT is at least 1, CSLECT returns SELVAL(SELOPT) and adds 1
            to SELOPT, cycling back to 1 at SELMAX.

       Parameters
           Z

                     Z is COMPLEX
                     The eigenvalue Z.
