rssn: A Comprehensive Scientific Computing Library for Rust

Crates.io Docs.rs License

rssn is an open-source scientific computing library for Rust, combining symbolic computation, numerical methods, and physics simulations in a single ecosystem.
It is designed to provide a foundation for building a next-generation CAS (Computer Algebra System) and numerical toolkit in Rust.

✨ Features

The library is organized into five major components:

  • Symbolic:
    Computer algebra system foundations, differentiation & integration, group theory, Lie algebras, polynomial algebra, PDE/ODE solvers, Grobner bases, quantum mechanics operators, graph algorithms, and more.

  • Numerical:
    Linear algebra, optimization (Rastrigin, Rosenbrock, Sphere, Linear Regression), numerical integration, probability distributions, FFT, combinatorics, special functions, PDE solvers (heat, wave, Schrödinger 1D–3D), root finding, and statistical analysis.

  • Physics:
    Simulation modules covering FDM/FEM/FVM solvers, multigrid methods, molecular mechanics (SPH), electrodynamics (FDTD), Navier–Stokes fluid dynamics, relativity (geodesics, Schwarzschild), elasticity, quantum simulations, and more.

  • Output:
    Pretty-printing, LaTeX/Typst export, NumPy-compatible I/O, and plotting utilities (2D/3D surfaces, vector fields, parametric curves).

  • Plugins:
    Optional extensions (enabled with the full feature).

🚀 Quick Start

Add rssn to your Rust project:

cargo add rssn

Then start exploring:

use rssn::symbolic::calculus::differentiate;
use rssn::numerical::matrix::Matrix;

fn main() {
    let expr = "x^2 + sin(x)";
    let d = differentiate(expr, "x");
    println!("d/dx of {} = {}", expr, d);

    let m = Matrix::identity(3);
    println!("3x3 Identity Matrix: {:?}", m);
}

For more examples, see the project repository.

💰 Sponsorship & Donations

Scientific computing requires heavy resources for CI/CD, benchmarking, and cloud testing. You can support development via GitHub Sponsors.

Enterprise sponsors will receive:

  • Priority support from the core maintainers
  • Ability to request features
  • Direct collaboration on integration needs

Excess donations will be redirected to upstream Rust ecosystem projects (e.g., rust-LLVM) or community initiatives.
