    Purpose   
    =======   

    This function is used to determine what eigenvalues will be   
    selected.  If this is part of the test driver SDRGSX, do not   
    change the code UNLESS you are testing input examples and not   
    using the built-in examples.   

    Arguments   
    =========   

    AR      (input) REAL   
            The numerator of the real part of a complex eigenvalue   
            (AR/BETA) + i*(AI/BETA).   

    AI      (input) REAL   
            The numerator of the imaginary part of a complex eigenvalue   
            (AR/BETA) + i*(AI).   

    BETA    (input) REAL   
            The denominator part of a complex eigenvalue   
            (AR/BETA) + i*(AI/BETA).
