nalgebra is a general-purpose linear algebra library for Rust providing statically-sized and dynamically-sized vectors and matrices, along with strongly typed geometric entities like points, rotations, quaternions, isometries, and projections. It ships companion crates for graphics-oriented APIs (nalgebra-glm), sparse matrices (nalgebra-sparse), and optional LAPACK-backed decompositions (nalgebra-lapack), and compiles for WASM and embedded no_std targets.

Use cases

• perform vector and matrix math in Rust
• compute matrix decompositions and solve linear systems
• handle 3D rotations, quaternions, and isometries for game or graphics engines
• work with sparse matrices in CSC/CSR format
• use linear algebra in WebAssembly or embedded no_std projects
• replace GLM-style math API in Rust graphics programming

When to choose

• you need fast, comprehensive linear algebra in Rust with strong typing for dimensions and geometric transforms
• you target wasm or embedded environments without the standard library
• you want a GLM-like API for computer graphics via nalgebra-glm
• you need both stack-allocated fixed-size and heap-allocated dynamic-size matrices

When to avoid

• you need a full numerical computing ecosystem like NumPy/SciPy with plotting, statistics, and arrays beyond linear algebra
• you primarily need GPU-accelerated or distributed linear algebra at massive scale
• your project is not written in Rust
