In my efforts to bring further functionality to the web, I have today explored the possibility of porting the versatile Meta.Numerics class library to Silverlight. Luckily enough, this was quite an easy task.
I only had to omit serialization support via the Serializable attribute, and the ADO.NET coupling of the various statistical Sample classes, otherwise the Silverlight class library built without issues.
The Meta.Numerics class library is distributed under the Microsoft Public License. I soon hope to find a suitable way for making the Silverlight library modifications public, either via Github or CodePlex.
