New Post: denseSvd returns defferent results each time
What do you mean by "Managed or native SVD"? If you were you using the MKL native linear algebra provider or not. I just tried it and it also returns the same result between runs. I'm using a similar...

It's ok - thank you very much for taking the time and trying to help. Guy
View ArticleNew Post: API Reference out-of-date
The API Reference is terribly out of date -- based on 2.1.2.21 when the current version is 2.5.0.27. I say terribly because the source-embedded documentation has apparently gotten much better over that...

Indeed, I've just regenerated it for v2.5.0. I also fixed a bug in docu (some open source doc generation engine we use) that caused a lot of methods to be omitted previously, so the reference should be...

So it appears that docu doesn't put show documentation for inherited members -- it would be handy if it included their documentation (as doxygen can be instructed to do) or at least linked to their...

Yes, I've noticed that as well. It also doesn't flag obsolete members yet which can be confusing (e.g. DenseMatrix.Data vs .Values). I'm working on a fix within docu, not too hard but needs some...

I've fixed docu and uploaded a new build. It should now include inherited members, list static methods separately and warn prominently on anything that has been marked as obsolete.

Hi, I added the Brent root solver to my copy of the source code. Would you add it to the repository for others to use? Candy

Hi Candy, Certainly, that would be welcome. How can we get hold of your work? Thanks, Christoph

I created a fork, and pushed changes there.https://git01.codeplex.com/forks/candychiu/rootsolver Internally I used MbUnit for unit testing. The simple test case needs modification and extension.

That worked nicely, I've pulled it to mainline already. Thanks, Christoph
View ArticleNew Post: Lognormal sampling
I'm trying to generate lognormal samples. When I do something like this: double sample = LogNormal.Sample(aRandomGenerator, 0.000001, 0.000001) I get numbers back close to 1, but I was expected them to...

It looks like I get the correct result if I do this: double sample = Math.Log(LogNormal.Sample(aRandomGenerator, 0.000001, 0.000001)); Why's that?

From a first look it seems it is working correctly. The mu/sigma parameters do not specify the mean and standard deviation of the variable (these are called "Mean" and "StdDev"), but of the natural...
