New Post: Using MKL has no effect
I can't get the native provider to work (I don't see any performance improvement) Is there a way to tell that it's being used, other than the performance improvement? Code is as follow: mRef is a...

A bit more info: I know for a fact that if the libiomp5md.dll and MathNet.Numerics.MKL.dll file aren't included, an exception is raised. dV is typically 500 elements long. mRef can vary from a 1x500 to...

A) What are the actual instance types of the involved matrices and vectors? I.e. are there any which are not DenseMatrix/DenseVector? B) Would it be possible to upgrade to Math.NET Numerics v2.6.2?...

Hello there! Please help me use Math.Net multi-regression functions. I am working with the following code: var xdata = new double[,]{ {1, 36, 66, 45, 32}, {1, 37, 68, 12, 2}, {1, 47, 64, 78, 34}, {1,...

Looks like it was working all along, the improvement became obvious when running without the debugger attached. A) They are all DenseMatrix/DenseVector B) Yes, is 2.6.2 released as NuGet, or do I need...

Thanks for the update. Yes, 2.6.2 is on NuGet. It's the newest v2 release. You may also have a look at the v3 pre-releases already - they are still alpha and will thus change, but these changes will be...

Hi, I'm trying to use the Brent algo to find the minima for a given function. It converges very quickly, however it doesn't "stop" once the result is close enough. I need it to stop at the nearest...

Actually stepping through it again with the accuracy set to 0.01 I end up hitting return false; if (xMid == xMidOld) { // accuracy not sufficient, but cannot be improved further return false; } The...

Hi, StudentT.InvCDF has been added in master a few weeks ago and will be available in the next alpha (v3.0.0-alpha8). Thanks, Christoph

How would one check whether two vectors are linearly dependent using Math.NET Numerics? P.S. Is this the correct place to ask this?

Hi Christoph,Thx for the information. It's a good news. Do you know when the V3.0.0-alpha8 will come out?By the way, I have been using http://www.mathdotnet.com/ for 4 days, it's a great product. Easy...

We probably should add a method for that. In the meantime you can, for example, check whether the determinant of the 2x2 matrix of the vector's scalar products is zero:var a =...

I see, thanks for the answer. Yes,a linear dependency test for only 2 vectors would probably be nice. For my own project I also need support for vectors with homogeneous coordinates. Are there any...

Hello, I would be also very interested by this feature and would be willing to help. What's the status of the fork that has been created? Is there a to-do list or something? Thanks! Xavier

No, it is not right now, since the .Net numeric type precision is not supposed to be machine dependent (assuming IEEE754 binary64, even though CPU registers may have higher precision. In memory, a...
