nalgebra-sparse-linalg

Sparse linear algebra iterative solvers for nalgebra_sparse.

Overview

nalgebra-sparse-linalg provides iterative methods for solving large, sparse linear systems of equations, with a focus on compatibility with the nalgebra_sparse crate. The initial release includes a Jacobi iterative solver for diagonally dominant matrices.

Features

Jacobi iterative solver for sparse matrices in CSR format.
Generic over scalar types (e.g., f32, f64).
Simple API compatible with nalgebra_sparse's matrix and vector types.

Usage

Add this to your Cargo.toml:

[dependencies]
nalgebra-sparse-linalg = "0.1"
nalgebra-sparse = "0.9"
nalgebra = "0.32"

Example:

use nalgebra_sparse::{na::DVector, CsrMatrix};
use nalgebra_sparse_linalg::iteratives::jacobi::solve;

let a = CsrMatrix::identity(3);
let b = DVector::from_vec(vec![1.0; 3]);
let result = solve(&a, &b, 100);
assert!(result.is_some());
