C# 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

Shouldn't the following code work?

```
vector1.InnerProduct(vector2);
```
