EnglishWhat is Math.NET?
Updated
Math.NET is an open-source initiative that builds and maintains toolkits covering fundamental mathematics for .NET developers. It targets both advanced and everyday mathematical needs, so it fits anyone working in C#, F#, or other .NET languages who needs numerical routines, symbolic algebra, signal processing, or geometry without writing those foundations from scratch. The project is distributed through GitHub and NuGet, with discussions hosted at @MathDotNet.
What Math.NET actually is
Math.NET is not a single library. It is an umbrella project made up of several independent toolkits, each focused on a different area of mathematics. You adopt only the pieces you need.
| Toolkit | Focus | Notes from the project |
|---|---|---|
| Math.NET Numerics | Numerical computing | Special functions, linear algebra, probability models, random numbers, interpolation, integral transforms, and more |
| Math.NET Symbolics | Computer algebra | A basic open-source CAS for .NET and Mono, written entirely in F# |
| Math.NET Filtering | Signal processing | Previously named Neodym; digital filter design, applying filters to data streams via data converters, and digital signal generators |
| Math.NET Spatial | Geometry | Aims to become a geometry library for .NET and Mono |
There are also archived projects that are no longer active: Math.NET Iridium, Math.NET Classic, Math.NET Linq Algebra, and Math.NET Yttrium. Treat these as historical rather than as current choices.
Who it is for
The stated audience is .NET developers, from those handling routine numerical tasks to those needing more advanced scientific or engineering computation. If your work involves solving linear systems, generating random variates, designing filters, or manipulating symbolic expressions inside a .NET codebase, these toolkits are aimed at you.
How to get and use it
The project points to GitHub and NuGet as its distribution channels. In practice that means you add the relevant package through NuGet rather than downloading source manually, and you follow or contribute to development on GitHub. The @MathDotNet discussions channel is where community questions and project conversation happen.
Because each toolkit covers a distinct domain, the practical first step is to identify which one matches your task — Numerics for general computation, Symbolics for algebra, Filtering for signal work, Spatial for geometry — and then bring in only that package.
A note on scope
The project describes Symbolics as "basic," so it is not positioned as a full-featured computer algebra system. Spatial is described as aiming to become a geometry library, which signals it may be less mature than the numerical toolkit. Numerics lists the broadest set of covered topics and is the most clearly defined of the group.
