linalg-rs - Linear Algebra library written in rust

Linear algebra in Rust!

Parallelized using rayon with support for many common datatypes, linalg-rs tries to make matrix operations easier for the user, while still giving you as the user the performance you deserve.

Regular matrices have many features already ready, while Sparse ones have most of them. Whenever you want to switch from one to the other, just call from_dense, or from_sparse to quickly and easily convert!

Need a feature? Please let me/us know!W

Even have custom declarative macros to create hashmap for your sparse matrices!

Examples

Dens Matrices

use linalg_rs::{LinAlgFloats, Matrix};

fn main() {
    let a = Matrix::<f32>::randomize((8, 56));
    let b = Matrix::<f32>::randomize((56, 8));

    let c = a.matmul(&b).unwrap();

    let res = c.sin().exp(3).unwrap().pow(2).add_val(4.0).abs();

    // To print this beautiful matrix:
    res.print(5);
}

Sparse Matrices

use std::collections::HashMap;
use linalg_rs::{SparseMatrix, SparseMatrixData};

fn main() {
    let indexes: SparseMatrixData<f64> = smd![
        ((0, 1), 2.0),
        ((1, 0), 4.0),
        ((2, 3), 6.0),
        ((3, 3), 8.0)
    ];

    let sparse = SparseMatrix::<f64>::new(indexes, (4, 4));

    sparse.print(3);
}
