The function `ScalarMinimizationResult FindMinimum(IScalarObjectiveFunction objective, double lowerBound, double upperBound)` (in Numerics.Optimization) does not respect the `lowerBound` argument. In my example of `FindMinimum(somefunction, 0.05, 0.4)` the GS-algorithm expands below 0.05 and...
I am trying to Inverse 16x16 matrix, but the resulting values are **NaN/Infinity/-Infinity**. >var json = File.ReadAllText("data.json"); >var arr = JsonConvert.DeserializeObject(json); > >var matrix = Matrix.Build.Dense(16,16, arr); >var inverted =...
Given the following complex matrix: ``` (0., 0.) (1., 0.) (0., 0.) (0., 0.) (2.25, 0.) (0., 0.) (0., 0.) (0., 0.) (0., 0.) (0., 0.) (0., 0.) (1., 0.)...
I am trying to replicate the FFT analysis of a Python code in C# using MathNet.Numerics.Fourier.Forward of a Sin signal. Using a number of samples of 5x10^4 the resulting FFT...
I'm porting some IMSL-based Fortran code to C#, including some calls to [CSIEZ](https://docs.roguewave.com/en/imsl/fortran/current/html/fnlmath/index.html#page/FNLMath/mch3.05.09.html), which does cubic spline interpolation using the "not-a-knot" condition. I'm not terribly knowledgeable about splines, so I...
Hi, I've been struggling with this issue for a couple of hours now. I'm trying to use MKL for simple linear algebra calculations (matrix & vector multiplication mostly), and I...
Hi, It would be nice to use `params T[]` in the constructor for `Vector`, that way one could simply declare a vector as `new Vector(1.1, 2.2, 3.3)` instead of `Vector.Build.DenseOfArray(new...
Hi 😊 I am using the ODE solvers in mathnet-numerics to solve a system of ODE, and I have encountered several times that I need to append two vectors along...
Hello Team, I am just curious if there is a Special "non-linear" generalized Regression method in Math.Net so user can do fits with any nonlinear function / model? In the...
https://github.com/mathnet/mathnet-numerics/blob/master/src/Numerics/SpecialFunctions/GeneralizedHyperGeometric.cs Been trying to use the 1F1 function, but ran into problems once I found out the z parameter is of type int. There does not seem to be any...
