TOpenCLVector::Difference Method

Overload List

#SignatureDescription
1TOpenCLMtxVec *Difference(TOpenCLMtxVec *Vec, int VecIndex, int Index, int Len);Difference.
2TOpenCLVector *Difference(TOpenCLMtxVec *Vec, int Lag = 1);The difference between two succesive vector elements.

Overload 1: TOpenCLMtxVec *Difference(TOpenCLMtxVec *Vec, int VecIndex, int Index, int Len);

Difference.

#NameTypeDescription
1VecTOpenCLMtxVec *
2VecIndexint
3Indexint
4Lenint
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 TOpenCLBase::Complex properties of the calling vector must be set explicitly. The following formula is used to calculate the difference:

Δ[k]=Vec[k+1]Vec[k],0k<Vec.Length1\Delta [k] = \text{Vec}[k+1] - \text{Vec}[k], \quad 0\leq k < \text{Vec.Length}-1

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

Overload 2: TOpenCLVector *Difference(TOpenCLMtxVec *Vec, int Lag = 1);

The difference between two succesive vector elements.

#NameTypeDescription
1VecTOpenCLMtxVec *
2Lag = 1int
Remarks:

Store the results in the calling vector. The TOpenCLBase::Length of the calling vector is set to one less the length of Vec and TOpenCLBase::Complex property is set to Vec.Complex. The following formula is used to calculate the difference:

The Length of calling vector is automatically decremented by one.
