TMtx::Difference Method

TMtxVec Difference(TMtxVec Vec, int VecIndex, int Index, int Len, int Lag = 1);

Difference.

#	Name	Type
1	Vec	TMtxVec *
2	VecIndex	int
3	Index	int
4	Len	int
5	Lag = 1	int

Remarks:

Calculate the difference for Vec elements [VecIndex]..[VecIndex+Len-1] and store the results in the calling object elements [Index]..[Index+Len-1]. Size and TMtx::Complex properties of the calling vector must be set explicitly. The following formula is used to calculate the difference:

\Delta [k] = \text{Vec}[k+1] - \text{Vec}[k], \quad 0\leq k < \text{Vec.Length}-1

An exception is raised if TMtx::ConditionCheck is True and array borders are overrun or underrun.
