Matrix Operations in C#

[Guest]

Hi
I'm trying to do matrix operations in C#. Is there a API that can be used.
Like for eg. I have 2 vectors
Vector A: [1 0 1 0]
Vector B : [0 1 0 1]
Vector B - Vector A = [-1 1 -1 1]

Should just be using ArrayList for these.

Considering that there could be at least 96 elements in each array list and
this

comparison should be done for a minimum of 200 ArrayList. How fast would
this operation be if I was scanning thru the list everytime.

I guess you'll have to devise your own classes for this.

The built-in Matrix class in .NET encapsulates a 3-by-3 affine matrix
that represents a geometric transform to be used with GDI+.

I've used the Mathnet Numerics library before. It works fine and has a
whole load of stuff in it.

Google is a wonderful tool. A search for "mathnet numerics" found this
at the top of the is:

http://nmath.sourceforge.net/doc/numerics/MathNet.Numerics.html

For the download page etc, just go to:
http://nmath.sourceforge.net

Don't forget the DirectX managed and unmanaged namespaces and classes. Lots
and lots of good stuff there.
