sprs, sparse matrices for Rust

sprs implements some sparse matrix data structures and linear algebra algorithms in pure Rust.

The API is a work in progress, and feedback on its rough edges is highly appreciated :)

Features

Structures
  • CSR/CSC matrix
  • triplet matrix
  • Sparse vector
Operations
  • sparse matrix / sparse vector product
  • sparse matrix / sparse matrix product
  • sparse matrix / sparse matrix addition, subtraction
  • sparse vector / sparse vector addition, subtraction, dot product
  • sparse/dense matrix operations
Algorithms
  • Outer iterator on compressed sparse matrices
  • sparse vector iteration
  • sparse vectors joint non zero iterations
  • simple sparse Cholesky decomposition (requires opting into an LGPL license)
  • sparse triangular solves with dense right-hand side

Examples

Matrix construction

  use sprs::{CsMat, CsMatOwned, CsVec};
  let eye : CsMatOwned<f64> = CsMat::eye(3);
  let a = CsMat::new_csc((3, 3),
                         vec![0, 2, 4, 5],
                         vec![0, 1, 0, 2, 2],
                         vec![1., 2., 3., 4., 5.]);

Matrix vector multiplication

Read the full README
  use sprs::{CsMat, CsVec};
  let eye = CsMat::eye(5);
  let x = CsVec::new(5, vec![0, 2, 4], vec![1., 2., 3.]);
  let y = &eye * &x;
  assert_eq!(x, y);

Matrix matrix multiplication, addition

  use sprs::{CsMat, CsVec};
  let eye = CsMat::eye(3);
  let a = CsMat::new_csc((3, 3),
                         vec![0, 2, 4, 5],
                         vec![0, 1, 0, 2, 2],
                         vec![1., 2., 3., 4., 5.]);
  let b = &eye * &a;
  assert_eq!(a, b.to_csr());

Minimum Supported Rust Version

The minimum supported Rust version currently is 1.64. Prior to a 1.0 version, bumping the MSRV will not be considered a breaking change, but breakage will be avoided on a best effort basis.

Compare with similar projects

Order: strongest tier first, then most downloads, then name, with unmeasured values last. A library counts downloads over 30 days. An app counts binary downloads per release. An app with none counts its crate downloads over 30 days. ML Rust runs this catalogue, so its closest project always gets a row.

Why FeaturedIt passes every Featured gate.

What it meets

  • It has 63 active dependents and 45 new dependents in 365 days. Featured needs 11 active dependents or 9 new dependents in 365 days.
  • Active dependents are at 100% of their peak. Featured needs at least 50%.
  • Docs are present. The release commit or a manifest ties the crate to the repository.
  • No vulnerability advisory stays unpatched past the grace window. At least one version is neither a prerelease nor 0.0.x.
  • The last activity is on 20 Oct 2026, 20 days ago. The rules expect an update within 1800 days. Dormancy rule

Exact rules: Featured library. The check on applied thresholds version 9.

Every rule outcome, as the check records it
  • expected-interval: version 0.11.6 base 450, doubled for 974572 downloads per month, doubled for 63.17 active users: E = 1800 days
  • dormancy: last activity 2026-10-20, 20 days ago, E = 1800: active
  • featured: featured: active_users 63.17, new_adopters 45, former_glory 1
