Crate rlst_suitesparse 

SuiteSparse bindings for RLST sparse matrices.

This crate currently provides a safe UMFPACK interface for solving real and complex double-precision systems stored as rlst::sparse::csr_mat::CsrMatrix. SuiteSparse must be installed natively. Set SUITESPARSE_PATH to its installation prefix when it is not discoverable in a standard location.

use rlst::{FromAij, rlst_dynamic_array};
use rlst::sparse::csr_mat::CsrMatrix;
use rlst_suitesparse::UmfpackFactorize;

let matrix = CsrMatrix::from_aij(
    [2, 2],
    &[0, 0, 1, 1],
    &[0, 1, 0, 1],
    &[4.0, 1.0, 2.0, 3.0],
);
let numeric = matrix.factorize()?;
let mut rhs = rlst_dynamic_array!(f64, [2]);
rhs[[0]] = 1.0;
rhs[[1]] = 1.0;
let solution = numeric.solve(&rhs)?;
assert!((solution[[0]] - 0.2).abs() < 1e-12);
assert!((solution[[1]] - 0.2).abs() < 1e-12);
