Gonum

Gonum is an open‑source collection of numeric libraries for the Go programming language, designed to provide robust, production‑quality numerical computing capabilities. Built to fit Go’s emphasis on simplicity and performance, Gonum offers a modular set of packages that implement a wide range of mathematical and statistical routines used in scientific computing and data analysis.

The core packages cover key areas of numerical computing. The mat package provides matrix and linear algebra functionality, including dense and sparse matrices and common decompositions such as LU, QR, eigenvalue, and singular value decomposition. The stat package offers basic statistics and hypothesis testing, while stat/distuv provides probability distributions and random variates. The optimize package supplies optimization algorithms, and the fit package supports curve fitting and regression. Additional packages address numerical integration, interpolation, and other numerical methods. Plotting is available through a separate Gonum project (gonum.org/v1/gonum/plot) that can be used alongside Gonum computations.

Usage of Gonum is common among Go developers who need numerical computing within Go applications, including data analysis, simulations, optimization, and algorithm development. The project emphasizes Go idioms, safety, and performance, aiming to provide a stable, well‑tested foundation for scientific computing in Go.

Development and licensing: Gonum is maintained by an open‑source community with regular releases and Go module support. It uses a permissive open‑source license.
