Crate sprs [−] [src]

sprs

sprs is a sparse linear algebra library for Rust.

It features a sparse matrix type, CsMat, and a sparse vector type, CsVec, both based on the compressed storage scheme.

All matrix algebra operations are supported, and support for direct sparse solvers is planned.

Examples

Matrix construction

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

Matrix vector multiplication

use sprs::{CsMat, CsVec};
let eye = CsMat::eye(sprs::CSR, 5);
let x = CsVec::new_owned(5, vec![0, 2, 4], vec![1., 2., 3.]).unwrap();
let y = &eye * &x;
assert_eq!(x, y);

Matrix matrix multiplication, addition

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