ZLCTES
Purpose:
!> !> ZLCTES returns .TRUE. if the eigenvalue Z/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 ZDRGES to test whether the driver !> routine ZGGES successfully sorts eigenvalues. !>
Parameters
Z
!> Z is COMPLEX*16 !> The numerator part of a complex eigenvalue Z/D. !>
D
!> D is COMPLEX*16 !> The denominator part of a complex eigenvalue Z/D. !>
