New Post: new user question
Hi Christoph,When I try your suggestion,var a = new Double.DenseVector(newdouble[] {1,2,3});I get the following error: "The type name 'DenseMatrix' does not exist in the type 'double'"I guess this is...

Sorry, my mistake - that trick only actually works if you're inside the MathNet.Numerics.LinearAlgebra namespace. Please consider cuda's approach instead with an alias, or more general e.g.:using...

Just for reference, its the first one (BiCgStab) that is off, as verified with:pascal3.LU().Solve(uVec); pascal3.QR().Solve(uVec);

I actually don't know that much about our iterative solvers and how they (are supposed to) behave numerically myself, but some quick experiments show that it suddenly converges if we increase the...

I guess the goal of descriptive statistics is to compute a whole bunch of stats in as few passes over the data as possible. It has proven very useful to me many times; the only slightly unsatisfactory...

The unit tests hang on the solvers (direct and iterative) and about 25 non-solver tests fail under Mono 2.10 on Ubuntu 10.10. Most are precision and culture problems, and a couple are due to differing...
