Overload 2: TMtxVec *Inv(int Index, int Len);

Calculate the inverse of calling object elements [Index]..[Index+Len-1] in-place.

#	Name	Type	Description
1	Index	int
2	Len	int

Remarks:

An exception is raised if array borders are overrun/underrun.

Overload 3: TMtxVec *Inv(const double Threshold);

Calculate the inverse of all calling object elements in-place. The computation occurs after first limiting the magnitude of each element by the lower bound of Threshold.

#	Name	Type	Description
1	Threshold	const double

Remarks:

The limiting operation is performed to avoid division by zero. Since Threshold represents a magnitude, it is always real and must always be positive.

For complex versions, the magnitude of the input is limited, but the phase remains unchanged. Zero-valued input is assumed to have zero phase.
