libmat-rs

Rust bindings for libmat, an stb-style single-header linear algebra library in pure C.

Usage

Add to your Cargo.toml:

[dependencies]
libmat-rs = "0.1"

use libmat_rs::Mat;

let a = Mat::from_slice(2, 2, &[1.0, 2.0, 3.0, 4.0]);
let b = Mat::eye(2);
let c = a.mul(&b);

let eig = a.eigen_sym();

Matrices use column-major storage (BLAS-compatible).

API

Function Description
Mat::new(rows, cols) Zero-initialized matrix
Mat::from_slice(rows, cols, data) Matrix from column-major slice
Mat::eye(dim) Identity matrix
mat.mul(other) Matrix multiplication
mat.add(other) Element-wise addition
mat.at(row, col) Element access
mat.eigvals() Eigenvalues (general)
mat.eigvals_sym() Eigenvalues (symmetric)
mat.eigen() Eigendecomposition (general)
mat.eigen_sym() Eigendecomposition (symmetric)

Coverage

This crate exposes a subset of libmat's functionality. The underlying C library supports many more operations (SVD, Cholesky, QR, LU, solvers, norms, SIMD kernels, etc.) that are not yet wrapped. Contributions are welcome.
