Scalar product of two real arrays.

Syntax
C#
Visual Basic
public double DotProd([In] TOpenCLMtxVec Vec);
Remarks

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.

Example
using Dew.Math; using Dew.Math.Units; namespace Dew.Examples() { void Example() { clMtxVec.TOpenCLMatrix a,b; clMtxVec.CreateIt(out a, out b); try { a.Size(2,2, TclFloatPrecision.clFloat, false); b.Size(2,2, TclFloatPrecision.clFloat, false); a.CopyFromArray(new double[] {1,2,3,4}); b.CopyFromArray(new double[] {4,3,2,1}); double prod = a.DotProd(b); // = 1*5 + 2*6 + * 3*7 + 4*8 } finally { clMtxVec.FreeIt(ref a,ref b); } } }
