TVecInt::Difference Method

TVecInt Class

Overload List

#SignatureDescription
1TMtxVecInt *Difference(TMtxVecInt *Vec, int VecIndex, int Index, int Len, int Lag = 1);Difference.
2TVecInt *Difference(int Lag = 1);The difference between two succesive vector elements.
3TVecInt *Difference(TMtxVecInt *Vec, int Lag = 1);Calculate the difference for all Vec elements.

Overload 1: TMtxVecInt *Difference(TMtxVecInt *Vec, int VecIndex, int Index, int Len, int Lag = 1);

Difference.

#NameTypeDescription
1VecTMtxVecInt *
2VecIndexint
3Indexint
4Lenint
5Lag = 1int
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 of the calling vector must be set explicitly. The following formula is used to calculate the difference:

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

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

Overload 2: TVecInt *Difference(int Lag = 1);

The difference between two succesive vector elements.

#NameTypeDescription
1Lag = 1int
Remarks:

Calculate the difference for all calling vector elements. The following formula is used to calculate the difference:

The Length of calling vector is automatically decremented by one.

Overload 3: TVecInt *Difference(TMtxVecInt *Vec, int Lag = 1);

Calculate the difference for all Vec elements.

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

Store the results in the calling vector. The TVecInt::Length of the calling vector is set to one less the length of Vec.
