Finding a dot product

Finding a dot product

int[] v1 = {1,2,3};
int[] v2 = {3,2,1};
// dot product of vector
int[] dotProducts = v1.DotProduct(v2);
// output:
// 3
// 4
// 3

public static int[] DotProduct(this int[] vector1, int[] vector2)
{
    return vector1.Zip(vector2, (x, y) => x*y).ToArray();
}
