ZLCTES
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.
[in] | Z | Z is COMPLEX*16 The numerator part of a complex eigenvalue Z/D. |
[in] | D | D is COMPLEX*16 The denominator part of a complex eigenvalue Z/D. |
