title: C#: Declaring and Using XNA Vectors for Matrix Multiplication, et. al
body: <p>I am trying to declare and use XNA Vectors for Matrix Multiplication, Summation, etc. in C#.</p>
  
  <p>Those will be used for Image processing to make it faster than regular SetPixel and GetPixel. However, I am always failing to find a working example and I tried many examples online but it seems I am missing something.</p>
  
  <p>Any help and sample code?</p>
  
  <p>Thanks!</p>
