New Post: Bisection Roots
I don't know recent VB very well, but the following seems to work in LinqPad:Dim f As Func(Of Double, Double) = Function(x) 2*x^2 - 2*x - 2 Bisection.FindRoot(f, 0, 2) ' 1.61803398874989...

I tried to use Hypergeometric cummulative distribution in Math.Net like below: var hyper = new MathNet.Numerics.Distributions.Hypergeometric(30,15,10); Console.WriteLine ("{0},",...

There was a fix on the hyper-geometric CDF semantics in the v3 branch, so if it had been originally intended (or simply was a bug), it is no more. With the current v3.0.0-beta01:var hyper = new...

Is Creating 3D DenseMatrix in Math.NET Possible? Like a 3x3x3 Matrix and initialize all elements to zero? I need to simulate something like Matlab's zeros(XM,YM1,ZM1) functions. Any help will be...

No. In Math.NET Numerics, matrices are really just matrices, not generalized multidimensional array-like data structures or tensors like in NumPy or MATLAB. Do you apply linear algebra routines to such...

There is no need to install anything. Assuming this is about Windows, just make sure both MathNet.Numerics.MKL.dll and libiomp5md.dll of the matching architecture (x86 vs x64) are in the same folder as...

Dear community member, In short, I have a series of 3 to 10 data points that will be used to represent a curve. For example:X=0, Y=10X=4, Y=7X=9, Y=12 X=16, Y=10 What I am trying to do is determine...
View ArticleNew Post: Is the reference point (x, y) above or below the non-linear equation?
The problem is that in order to decide whether the point is above or below, you need to define the exact curve instead of just a few points. The simplest approach would be to connect the closest points...
