New Post: Least Squares with bounds
Hi, First of all, great project! I was able to get going with it fairly quickly; it's well organized and straight forward. I'm attempting to convert some Matlab script to C# which uses the 'lsqlin'...

Hi Erik Unfortunately we have no linear programming related algorithms in Math.NET Numerics yet. This is one of the areas we want to cover some point in the future, but it is unlikely we'll get there...

Ah yes, we indeed only provide real versions for now. Adding complex versions is not currently at the top of the priority list, but yes, we would certainly accept and include them if contributed....

Hi Thomas, A weighted version of Fit.Polynomial using WeightedRegression (see also) could look like this:double[] PolynomialWeighted(double[] x, double[] y, double[] w, int order) { var design =...

Update: I've actually pushed PolynomialWeighted to master, so it will be available in the next alpha build.

Thanks Christoph, that is exactly what I needed ;-) Optimization hint (not sure): In WeightedRegression the lines likereturn x.TransposeThisAndMultiply(w*x).Cholesky().Solve(x.Transpose()*(w*y));can be...

Good catch, yes, we should rewrite it that way! Thanks, Chrstoph

I had been using Mathnet.Numerics for a personal project, now I have need to use a library I'd made using it in Unity3D, which uses Mono 2.6 (I believe), and does not have .Net 4.0 support. I have been...

Thanks for working this out! I wonder whether we can integrate this to mainline just like we integrate the portable builds, e.g. by defining a new compiler symbol "NET35" to conditionally include this...

Certainly sounds possible, it only took me an hour or so to do. It's a great library with a wonderful mix of reliability and license. I'm using it to find eigenvalues from a chebyshev approximation to...

The official release for .NET 3.5 would be great as it was such a widely used framework which many applications/source codes still rely on, specially those that can't be upgraded due to the usage of...

Thanks for the response and the tip; I will check it out. Erik

There is now a new Numerics-Net35 (and UnitTests-Net35) project, part of the portable solution. It compiles and the tests run, but there are still a few things to improve. Nevertheless, there might...
View ArticleNew Post: Q-less QR decomposition
In MATLAB (if A is sparse) R = qr(A) computes a Q-less QR decomposition and returns the upper triangular factor R. Does Math.NET Numerics support this Q-less decomposition for sparse matrices? Regards,...

Hi Oliver Not as part of our QR decomposition implementation. But as indicated in the MATLAB QR reference the triangular factor R can also be computed with the Cholesky decomposition: R = chol(A'*A),...
View ArticleNew Post: Is Neodym project dead?
Hi all, Looks from github like there's been no work on Math.Net Neodym for 5 years. Am I looking in the wrong place, or has Neodym died a slow death? thanks
View ArticleNew Post: Is Neodym project dead?
Most of Neodym is about to be merged into Math.NET Numerics for the next release, v3. Once there, Neodym will likely be discontinued, yes. Thanks, Christoph
