Remarks:

Divide each of Vec elements with corresponding elements in the calling object. Size and TVec::Complex property of the calling object are set automatically. The result is stored in the calling object.

The threshold parameter is used to prevent against division by zero and numerical instabilities in the follow on processing. All values of Vec smaller than Threshold will be replaced with Threshold.
