The package provides wrappers for [LAPACK] (Fortran). The usage of the package is explained here.
```rust 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); } ```
