Question Is there a package out with complex linear algebra operations, such as singular value decomposition?

I know this is quite a ridiculous request, but I am looking for a way to perform linear algebra operations on C# arrays, such as singular value decomposition, normalization, determinant, etc. Is there any such package out there? Simple operations like range scaling aren't too bad to code up, but I would appreciate not having to write an SVD code.

 

Looks like there is a C# wrapper for NumPy:
https://github.com/SciSharp/Numpy.NET
which can do what you want:
https://numpy.org/doc/stable/reference/generated/numpy.linalg.svd.html

That being said it uses things like

dynamic

which are not supported in IL2CPP.

 

So I haven't personally used any of this in my Unity projects but...

Math.Net exists, I don't know how compatible with Unity it is though:
https://numerics.mathdotnet.com/
https://numerics.mathdotnet.com/api/MathNet.Numerics.LinearAlgebra.Factorization/Svd`1.htm

Also Unity has their own Unity.Mathematics:
https://docs.unity3d.com/Packages/com.unity.mathematics@1.0/manual/index.html

And in it there is some allusions to svd:
https://github.com/Unity-Technologi...a7495db5005b96bd/src/Unity.Mathematics/svd.cs
https://github.com/search?q=repo:Unity-Technologies/Unity.Mathematics svd&type=code

Not sure what exactly you're hoping to do though. Maybe this will help.

 

I am cooking something, but it's not ready yet.
