Matrix::DotProd Method

Matrix Struct

double DotProd(TMtxVec *Vec, int VecIndex, int Index, int Len) const;

Scalar product of two real arrays.

#NameTypeDescription
1VecTMtxVec *
2VecIndexint
3Indexint
4Lenint
Remarks:

Returns the scalar product between Vec elements [VecIndex]..[VecIndex+Len-1] and calling object elements [Index]..[Index+Len-1]. An exception is raised if Vec and calling object Matrix::Complex property is True. An exception is raised if Matrix::ConditionCheck is True and array borders are overrun or underrun. The dot product is defined by the equation:

V⋅V=∑k=0Length−1V[k]⋅V[k]\text{V}\cdot \text{V} = \sum _{k=0} ^{\text{Length}-1}\text{V}[k]\cdot \text{V}[k]

Both objects must be of equal size. If they are not, the method will return the dot product of the largest sub-array.
