| Description | Yi = 1.0 / Xi, if | Xi | ≥ AbsMin,
Yi = 0, otherwise.
Complex versions:
Yi = 1.0 / Xi, if | Xi.Re | ≥ AbsMin.Re and | Xi.Im | ≥ AbsMin.Im,
1.0 / Xi.Re, if | Xi.Re | ≥ AbsMin.Re and | Xi.Im | < AbsMin.Im,
{0.0, −1.0 / Xi.Im}, if | Xi.Re | < AbsMin.Re and | Xi.Im | ≥ AbsMin.Im,
0, otherwise. |
