New Post: What Complex8 or Complex16 or Complex?
Christoph, Thank you for your excellent reply. I now have a better understanding of the current design and challenges of implementing my "simple" suggestions. ;-) Unfortunately, the math is over my...

Hello team, I have come across some behaviour in GammaUpperRegularized which I find suspicious: MathNet.Numerics.SpecialFunctions.GammaUpperRegularized(136.1375, 0.27) gives 1.0 and...

Yes, there indeed seems to be a bug on very large a values, in L294 (and also L184). The algorithm does detect that the values are large enough for the result to be 1.0 (or 0.0) within the required...

Fixed in mainline and thus made it into v2.6 which will be released quite soon. Thanks again for reporting. Thanks, Christoph

I am new to the world of FFT. Whenever new to an area, I like to experiment. Not knowing the performance characteristics of Transform, DFT.BluesteinForward, or DFT.Radix2Forward I wanted to do some...

Hi, This is certainly not by design/intended. It could either be a straight bug in the Bluestein implementation, or a numerical stability/robustness issue. Either way it should be fixed. Thanks for the...

Hi, Do you need the serialization to be in XML (for technical, standardization or whatever reasons), or would a simple text-based delimiter format like CSV or TSV work as well? If yes, I'd recommend to...

Hi Christoph! Thanks for your response! I do need to use XmlSerialization. I'll try to explain why. I have a bunch of assembiles reflcted at runtime and its information stored in a table for late...
View ArticleNew Post: Estimate mu and sigma
Hi, I have a sample of values, and I like to find the mu and sigma to fit to a logn distribution. I try to convert a Matlab code, that is using the lognfit method. Does anybody has an idea to do this?

Interesting setup! Quick question: would it be an option to use a surrogate object, i.e. make the XlsToMatrix function return something like a SerializableMatrix<T> instead of a Matrix<T>?...
