Vector.DotProd Method (TMtxVec)

Scalar product of two real arrays.

Pascal
function DotProd(const Vec: TMtxVec): double; overload;

Calculates the dot product (scalar value) of the calling object and Vec object and returns a real scalar value. The dot product is defined by the equation: 

 

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

var a,b: Vector; prod: double; begin a.SetIt(False,[1,2,3,4]); b.SetIt(False,[5,6,7,8]); prod := a.DotProd(b); // = 1*5 + 2*6 + * 3*7 + 4*8 end;
