# LAPACK [![Package][package-img]][package-url] [![Documentation][documentation-img]][documentation-url] [![Build][build-img]][build-url]

The package provides wrappers for [LAPACK] (Fortran).

## [Architecture]

## Example

```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);

}

```

## Development

The code is generated via a Python script based on the content the `lapack-sys`

submodule. To re-generate, run the following commands:

```sh

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

rustfmt src/lapack-sys.rs

```
