computing SVD of a matrix in c#

Sanju Singh

hello,
i wish to know, how matrices of any dimension can be created in c# ?as far as i now, we can create only 4x4 matrix using matrix3D data structure.
also,if this is possible, can we also find the SVD(singular value decomposition ) of a matrix directly in c# ? any help will be of great value.

thank you

I'd see if you can download it from CodePlex instead though, for some unknown reason, they only have version 3.2 and not the latest 3.3:

thanks Vulpes for the reply. I have a problem here. while checking for packages it needs to connect to the site through internet. I am getting a 403 error( may be because of the proxy settings of my college server). can you provide alternatives where i can download the package and use it by giving a reference thanks a lot

Although there were rumors at one time, that one might be added to the System.Numerics namespace, the .NET Framework still doesn't have a general purpose Matrix class.

You'll therefore need to look at third party packages for stuff such as matrix decomposition..

As it's both free and very extensive, I'd check out Math.NET Numerics which is available as a NuGet package:

http://www.nuget.org/packages/MathNet.Numerics/3.3.0

As it may not be immediately clear which method to call for SVD, I'd also read this thread I found on SO:
