Question

I need to perform some basic OLS regression using F#. To do this I need some Linear Algebra functions, but I’m confused as to what’s out there. I can’t find any way to invert a matrix. There is some documentation for a library called Microsoft.FSharp.Math.LinearAlgebra, but I don’t know if that exists anymore.

Answer 1

If you add the FSharp Powerpack to your project (in .NET references), you can use various functionality of the matrix library

edit: you also need to add the experimental library Fsharp.Powerpack.MathProviders, then you can call as follows

open    Microsoft.FSharp.Math let m = Matrix.create 10 10 1.2 let m2 = Experimental.LinearAlgebra.Inverse m
