Solution 1

There's even a MSDN article on that: "Matrix Decomposition"[^] (as suggested by the ThePhantomUpvoter, using Google you coud have quickly found it yourself).

Solution 2

This smells horribly of your homework - and we don't do your homework for you.

So, here is Google[^] with a list of sites talking about it, and giving algorithms.

The implementation is up to you: but it isn't exactly difficult!

You can use .NET framework :

http://msdn.microsoft.com/en-us/library/system.drawing.drawing2d.matrix.invert.aspx[^]

C#

Matrix myMatrix = new Matrix(3, 5, 1, 2, 2, 4);
myMatrix.Invert();

Or this function if you want to use double arrays
