New Post: Entropy
Hi everyone, I would like to calculate the entropy of a byte array - does the Math.NET Numerics framework provide a function to do that? Thanks a lot for your help! Best, Peter

This is scheduled for v3.0.0-beta2, see Issue 159. However, be aware that vectors have a fixed sized. Growing or shrinking them will always result in a full copy.

In v2, you can get a cubic spline interpolation by using the class directly from the MathNet.Numerics.Interpolation.Algorithms namespace:var spline = new CubicSplineInterpolation(new[] {0.0, 4.0, 9.0,...

Hello, I want to thank the team for the valuable work with Numerics. I would like to know what is the current status of mkl 11.1 upgrading? Since the SparseCompressedRowMatrixStorage<> is now...

Hi, See Issue 169, but feel free to open a separate issue for this. We may need to discuss how to expose this in the API and what to do in the managed case (where MKL is not available). Yes, creating a...

That looks very interesting, thanks for sharing! My latest stab at computer algebra, Math.NET Symbolics, actually uses straight recursive F# pattern matching (example: differentiation) which makes the...

I created csproj for Numerics and UnitTests to target .Net 4.5 by #1) Copy the existing csproj. #2) Change everything 4.0 to 4.5. #3) Change the GUID. Would you like these files? If not, do you have...

Hi Candy, What do we gain by compiling specifically against the .Net 4.5 base class libraries (in comparison to using the .Net 4.0 build in .Net 4.5 projects)? E.g. is there some functionality we could...

I am not quite sure. Can a .Net 4.5 project depend on a .Net 4.0 library? I remember running into version issues.

I'm curious too, because I'd like to solve a Power regression with multiple parameters. I know we can transform the power function to linear function y=a*(x1^b1)*(x2^b2) => log y= log a + b1*log x1...
