logical function dlctsx (double precision ar, double precision ai, double precision beta)

DLCTSX

Purpose:

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

Parameters

!>          AR is DOUBLE PRECISION
!>          The numerator of the real part of a complex eigenvalue
!>          (AR/BETA) + i*(AI/BETA).
!>

!>          AI is DOUBLE PRECISION
!>          The numerator of the imaginary part of a complex eigenvalue
!>          (AR/BETA) + i*(AI).
!>

BETA

!>          BETA is DOUBLE PRECISION
!>          The denominator part of a complex eigenvalue
!>          (AR/BETA) + i*(AI/BETA).
