FYI, I've just committed to mainline: all DenseMatrix and DenseVector classes now have static CreateRandom functions (replacing the old random template methods).

Just as a comment - I checked out the latest code, added the Serializable attributes to all Matrix and DenseMatrix classes, and serialization works as a charm. Very happy :-). If you get a chance to add that to the actual code at some point, I think others will find it useful.
Comments: Fixed

Well I'm not sure, I simply noticed it was out of place heh.

True. We weren't expecting anyone to do that, that is, users would always use the base NextXXX methods. The only case I can think of is that a user wants a Next method that returns a double. In that case, we should just extend the base class to provide it.
Is there any other case?

When I run the following code I get the exception : "Matrix dimensions must agree: op1 is 12x15, op2 is 12x1.". In my opinion this is correct. I'm running the latest public build v2.2.1.

using MathNet.Numerics.LinearAlgebra.Double;
...

SparseMatrix data = new SparseMatrix(12, 15);
data = (SparseMatrix) data.Random(12, 15, new MathNet.Numerics.Distributions.Normal());
DenseVector rez = (DenseVector) data.TransposeThisAndMultiply(new SparseVector(data.RowCount, 2.0));
Comments: Fixed in 164b0582457f. Thanks for pointing this out!

≫ Next: Updated Release: Math.NET Numerics v2.3.0 (Nov 25, 2012)

≪ Previous: Source code checked in, #eae02745503b

Common:

Continued major linear algebra storage rework, in this release focusing on vectors (previous release was on matrices)
Static CreateRandom for all dense matrix and vector types
Thin QR decomposition (in additin to existing full QR)
Consistent static Sample methods for continuous and discrete distributions (was previously missing on a few)
Portable build adds support for WP8
Various bug, performance and usability fixes

F# specific:

F# 3.0
Portable build now also for F# modules
F#: slicing support for matrices and vectors
F#: new modules for random numbers and distributions. Dropped "FSharp" module.

Native providers:

Updated MKL references

Also available as NuGet packages:
PM> Install-Package MathNet.Numerics
PM> Install-Package MathNet.Numerics.FSharp

Note: The portable package MathNet.Numerics.Portable has been dropped, as NuGet 2.1 properly supports portable builds in the main package.

If you absolutely require a signed library with a strong name:
PM> Install-Package MathNet.Numerics.Signed
