SymEngine is a fast symbolic manipulation library, written in C++

P(R*_{3, 0, 1}) specialized SIMD Geometric Algebra Library

MIRACL Cryptographic SDK: Multiprecision Integer and Rational Arithmetic Cryptographic Library is a C software library that is widely regarded by developers as the gold standard open source SDK for elliptic curve cryptography (ECC).

An efficient C++20 GPU numerical computing library with Python-like syntax

MATLAB MAT File I/O Library with support for MATLAB Class Object System

This project is a header-only C++ library designed for graphics mathematics, providing a comprehensive suite of vector, matrix, and quaternion types. It is built using template metaprogramming to generate mathematical primitives at compile time, eliminating the need for precompiled binary libraries and allowing for direct integration into existing build systems. The library is distinguished by its strict adherence to the OpenGL Shading Language specification, ensuring that mathematical results remain consistent across both CPU and GPU code. It provides specialized utilities for managing float

LibTomMath is a free open source portable number theoretic multiple-precision integer library written entirely in C.

linalg.h is a single header, public domain, short vector math library for C++

1loc is a JavaScript utility library and multifaceted toolkit providing a collection of single-line functions for common mathematical, string, date, and geometric operations. It functions as a set of functional programming helpers and data validation predicates designed to perform atomic transformations and validations. The project includes a geometry math library for calculating distances, angles, and spatial overlaps between points and rectangles, alongside a text manipulation library for casting, capitalizing, and analyzing string content. The toolkit covers broader capability areas inclu

Public domain single header fast Fourier transform for arbitrary array sizes, in about 100 lines of C code, which should be straightforward to understand.

Collection of self-contained header-only libraries for C++17

Boost.Multiprecision

A C/C++ header for parsing and evaluation of arithmetic expressions.

The Configurable Math Library

This library provides a self-contained and easy to use implementation of matrix container class. The main features include: - Full template parameterization with support for both real and complex data-types. - Lightweight and self-contained - single header, no dependencies outside of C++…

Simple discrete (DHMM) and continuous Hidden Markov Model (CHMM) library

This is a single header file inspired by stb.h by Sean Barrett with a bunch of useful statistical functions

Tiny header-only C++17 library for lat/lng geometry: distance, bearing, area, point-in-polygon and path proximity

Poisson Disk Points Generator

This is a header-only library, as such most of its functional documentation is contained within the "header section" of the source code in the form of comments. It is highly recommended that you read said documentation before using this library.
