LAPACK: Rust wrappers for the LAPACK library

LAPACK

The package provides wrappers for LAPACK (Fortran).

Architecture

Example

use lapack::*;

let n = 3;
let mut a = vec![3.0, 1.0, 1.0, 1.0, 3.0, 1.0, 1.0, 1.0, 3.0];
let mut w = vec![0.0; n as usize];
let mut work = vec![0.0; 4 * n as usize];
let lwork = 4 * n;
let mut info = 0;

unsafe {
    dsyev(b'V', b'U', n, &mut a, n, &mut w, &mut work, lwork, &mut info);
}

assert!(info == 0);
for (one, another) in w.iter().zip(&[2.0, 2.0, 5.0]) {
    assert!((one - another).abs() < 1e-14);
}

Development

The code is generated via a Python script based on the content the lapack-sys submodule. To re-generate, run the following commands:

./bin/generate.py > src/lapack-sys.rs
rustfmt src/lapack-sys.rs
