Unity and MathNET

I got this working.

Steps:

1) Create a folder called Assets/Plugins in your project.

2) go to

https://onedrive.live.com/?id=84F3672F8CDA3E91%21440210&cid=84F3672F8CDA3E91

and download the latest version of MatNet.Numerics.dll in zip format.

3) open the folder called Net35. Unity apparently only runs on this version of .net.

4) copy BOTH MathNet.Numerics.dll AND System.Threading.dll into Assets/Plugins.

Note: Don't touch anything in MonoDevelop. it should reference it automatically.

For me i was installing the newer .net version and I didn't realize it also needed System.Threading.dll. Once I got it in the above format it worked fine.

FYI: I'm on El Capitan OSX11.4 and Unity 5.3.4f1 personal.

Hope that helps! Adam

Well, this answer helped find the answer. I was able to get the Math.NET Numerics 3.9 running on unity on osx El Capitan.

Here are the steps I took:

• Install NuGet in Monodevelop using this tutorial https://www.youtube.com/watch?v=uHbAgbfgQdU

• Search for and install Math.NET Numerics using the NuGet plugin. That will also install System.Threading for which you'll have to accept a license agreement.

• Close monodevelop.

• NuGet creates a directory called packages under the project folder.

  • I copied "packages/TaskParallelLibrary.1.0.2856.0/lib/Net35" to a folder I named Assets/Libs.

  • Then I also copied the contents of "packages/MathNet.Numerics.3.9.0/lib/net35" to "Assets/Libs/Net35".

  • For correctness sake I placed the readmes and licenses under "Assets/Libs".

  • Finally I deleted the packages directory, and the file Assets/packages.config

That's it. You can test it by dragging the following script onto an object:

 using UnityEngine;
 using System.Collections;
 using Matrix = MathNet.Numerics.LinearAlgebra.Matrix<double>;
 using Vector = MathNet.Numerics.LinearAlgebra.Vector<double>;
 
 
 public class MathTest : MonoBehaviour {
     // *************************************************************************
     void Start() {
         Matrix A = Matrix.Build.DenseOfArray(new double[,] {
             {1,0,0},
             {0,2,0},
             {0,0,3}});
 
         Vector b = Vector.Build.Dense(new double[] {1, 1, 1});
 
         Vector x = A.Solve(b);
         Debug.Log("x = A^-1b: " + x);
     }
 }
 

You don't add the reference in monodevelop, you add the .dll to your unity project in the editor, which should then add it for use via the "using" statement. Here is the documentation for it:

MathNet requires .NET 4, which unity's version of monodevelop doesn't support.

If you manage to get it working, please tell me! I've been trying to use Iridium's stable distribution, but it's giving me bogus numbers. Iridium was discontinued in 2008 so I'm thinking it has lots of bugs. And I really don't want to implement my own probability distributions.

You could use Math.NET for Unity https://www.assetstore.unity3d.com/en/#!/content/77081 https://www.assetstore.unity3d.com/en/#!/content/77082
