Math.NET Numerics

Math.NET Numerics is an opensource numerical library for .Net, Silverlight and Mono.

Math.NET Numerics is the numerical foundation of the Math.NET initiative, aiming to provide methods and algorithms for numerical computations in science, engineering and every day use. Covered topics include special functions, linear algebra, probability models, random numbers, statistics, interpolation, integration, regression, curve fitting, integral transforms (FFT) and more.

In addition to the core .NET package (which is written entirely in C#), Numerics specifically supports F# 3.0 and 3.1 with idiomatic extension modules and maintains mathematical data structures like BigRational that originated in the F# PowerPack. If a performance boost is needed, the managed-code provider backing its linear algebra routines and decompositions can be exchanged with wrappers for optimized native implementations such as Intel MKL.

Supports Mono and .NET 4.0 and 3.5 on Linux, Mac and Windows, the portable build (PCL) also Silverlight 5, Windows Phone 8, .NET for Windows Store apps and Xamarin Android/iOS.

Math.NET Numerics is covered under the terms of the MIT/X11 license. You may therefore link to it and use it in both opensource and proprietary software projects. See also the license file in the root folder.

Release Notes & Changes

Installation Instructions

The recommended way to get Math.NET Numerics is to use NuGet. The following packages are provided and maintained in the public NuGet Gallery:

• MathNet.Numerics - core package, including .Net 4, .Net 3.5 and portable/PCL builds.
• MathNet.Numerics.FSharp - optional extensions for a better F# experience. BigRational.
• MathNet.Numerics.Data.Text - optional extensions for text-based matrix input/output.
• MathNet.Numerics.Data.Matlab - optional extensions for MATLAB matrix file input/output.
• MathNet.Numerics.MKL.Win-x86 - optional Linear Algebra MKL native provider.
• MathNet.Numerics.MKL.Win-x64 - optional Linear Algebra MKL native provider.
• MathNet.Numerics.Signed - strong-named version of the core package (not recommended).
• MathNet.Numerics.FSharp.Signed - strong-named version of the F# package (not recommended).

Alternatively you can also download the binaries in Zip packages, available on CodePlex:

• Binaries - core package and F# extensions, including .Net 4, .Net 3.5 and portable/PCL builds.
• Signed Binaries - strong-named version of the core package (not recommended).

Supported Platforms:

• .Net 4.0, .Net 3.5 and Mono: Windows, Linux and Mac.
• PCL Portable Profiles 47 and 136: Silverlight 5, Windows Phone 8, .NET for Windows Store apps (Metro).
• PCL/Xamarin: Android, iOS (not verified due to lack of license and devices)

Building Math.NET Numerics

If you do not want to use the official binaries, or if you like to modify, debug or contribute, you can compile Math.NET Numerics locally either using Visual Studio or manually with the build scripts.

• The Visual Studio solutions should build out of the box, without any preparation steps or package restores.
• Instead of a compatible IDE you can also build the solutions with msbuild, or on Mono with xbuild.
• The full build including unit tests, docs, NuGet and Zip packages is using FAKE.

How to build with MSBuild/XBuild

msbuild MathNet.Numerics.sln            # only build for .Net 4 (main solution)
msbuild MathNet.Numerics.Net35Only.sln  # only build for .Net 3.5
msbuild MathNet.Numerics.Portable.sln   # full build with .Net 4, 3.5 and PCL profiles
xbuild MathNet.Numerics.sln             # build with Mono, e.g. on Linux or Mac

How to build with FAKE

build.cmd   # normal build (.Net 4.0), run unit tests
./build.sh  # normal build (.Net 4.0), run unit tests - on Linux or Mac

build.cmd Build              # normal build (.Net 4.0)
build.cmd Build incremental  # normal build, incremental (.Net 4.0)
build.cmd Build full         # full build (.Net 3.5, 4.0, PCL)
build.cmd Build net35        # compatibility build (.Net 3.5)

build.cmd Test        # normal build (.Net 4.0), run unit tests
build.cmd Test full   # full build (.Net 3.5, 4.0, PCL), run all unit tests
build.cmd Test net35  # compatibility build (.Net 3.5), run unit tests

build.cmd Clean  # cleanup build artifacts
build.cmd Docs   # generate documentation, normal build
build.cmd NuGet  # generate NuGet packages, full build

build.cmd BuildNativex86   # build native providers 32bit/x86
build.cmd BuildNativex64   # build native providers 64bit/x64
build.cmd BuildNative      # build native providers for all platforms
build.cmd TestNativex86    # test native providers 32bit/x86
build.cmd TestNativex64    # test native providers 64bit/x64
build.cmd TestNative       # test native providers for all platforms

FAKE itself is not included in the repository but it will download and bootstrap itself automatically when build.cmd is run the first time. Note that this step is not required when using Visual Studio or msbuild directly.
