New Post: Noob Question: Solving a Matrix
Hi, Not entirely sure where your 4th variable comes in, but assuming you really want to solve the linear system A*x=y to x, or with actual numbers: 1*u + 0*v - 2*w = 0 2*u + 0*v + 0*w = 1 0*u + 2*v...

Thanks. Could you also copy the stack trace of the exception here? Thanks Christoph

Thanks. I'm building an asp.net app and I want to let user type a matrix into a textbox and then use ReadMatrix to convert it to a Matrix. Of course I can parse it myself, but thought I'd try the...

Thanks, that helps to pinpoint the problem. Could you retry but this time with a concrete matrix type in the reader?var mat = new DelimitedReader<DenseMatrix, double>(); (DenseMatrix from the...

Thanks, this is definitely helpful, but I'm still finding myself a bit stuck. Here's what I'm trying to do. I have an arbitrary number of variables in equations, such as: w = 2y 2w = z 2x = 3y + 2z So...

I figured it out. I just need to do something like: var z = x.QR().Determinent; x *= z; Thanks again for the help!

One more question! x.QR(). Determinant doesn't work for non-square matrices. Is there a way to do it I'm missing?

Since my last post series has probably gotten confusing as I've stated my problem, worked it out, and then stated a new one, I figured I'd just start a new thread. :) What's the best way to find the...

Hi Just started playing around with math.net and Native Linear Algebra Providers (MKL). I just want to clarify whether I have to purchase MKL from intel and recompile them as described on this site? I...

Thx Chris. As my team is using this lib, can we add such mathematical methods and check in? Do you have a list of methods you plan to add? I can help on this.

Yes, we accept contributions, and a covariance implementation would certainly be welcome. We use github to coordinate contributions, see also http://numerics.mathdotnet.com/ Thanks, Christoph

Hi, Christoph, Is the MKL dll checked into the repository? If not, where can I obtain it to use in Math .net? Thanks, Candy
View ArticleNew Post: Native Linear Algebra Providers
Hi Candy, The recommended way is to use the NuGet packages, see http://christoph.ruegg.name/blog/2013/2/3/mathnet-numerics-with-native-linear-algebra.html. Thanks, Christoph
