Dot Product on Matrices and Vectors

Question

I'm trying to get the dot product of two matrices, or vectors. I am using the Accord.net framework but I can't seem to find anything in the documentation that shows how to do this.

Here's an example:

double[] vector1 = { 1, 2, 3 };
double[] vector2 = { 3, 4, 5 };

Now I need to multiply them like so:

(1 * 3) + (2 * 4) + (3 * 5)

I assume this is possible, I just can't find the documentation that shows the method used for this.

Answer 1

Shouldn't the following code work?

vector1.InnerProduct(vector2);
