FsMath - Fast & Friendly Numerical Foundation for F#

FsMath is a lightweight maths library designed for modern F# workflows. It focuses on zero-friction interop with existing array-centric libraries ( FSharp.Stats, Math.NET Numerics, libtorch via TorchSharp, etc.) while giving you the performance head-room of SIMD-accelerated kernels and a clean, idiomatic F# API.

Why another numeric library?

Goal What it means in practice
Interop first Core types are just aliases or thin wrappers around native F# 'T [] arrays → you can pass data to any array-based .NET or C library without conversion or pinning.
Predictable memory layout Matrices are stored row-major (C-style) to line up with libtorch / TorchSharp, modern BLAS back-ends, and GPU kernels.
SIMD out-of-the-box Tight loops (dot, outer product, reductions ...) auto-detect hardware with SIMD support and pure-managed fallback otherwise.
F#-idiomatic API Pipelining, module functions, inline operators (.+, .*, transpose) and SRTP �type-class� dispatch keep your notebooks & scripts concise.

Key features

  • Vector / RowVector / Matrix - minimal, generic, and structural-equality aware.
  • High-level operators - .+, .-, .*, ./, outer product, Kronecker, hadamard, etc.
  • SIMD optimizes - dot products, outer products, reductions, and more.
  • Unsafe-free - everything is pure managed IL; no native dlls to ship.
  • Perfect interop - drop-in arrays to FSharp.Stats, TorchSharp, DiffSharp, and any BLAS/LAPACK P/Invoke you like.

Getting started

open FsMath
open FSharp.Stats.Distributions

// init vector
let v1  = vector [| 1.0; 2.0; 3.0 |]

// init vector with random samples (using FSharp.Stats)
let v2 = Array.init 3 (fun _ -> Continuous.ChiSquared.Sample 30.)

// SIMD-accelerated element-wise multiply
let result = v1 .* v2              

// interop: pass 'result' straight into e.g. TorchSharp tensor
