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

The package provides wrappers for [LAPACKE] (C).

## [Architecture]

## Example

```rust
use lapacke::*;

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 info;

unsafe {
    info = dsyev(Layout::ColumnMajor, b'V', b'U', n, &mut a, n, &mut w);
}

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

```sh
./bin/generate.py > src/lapacke-sys.rs
rustfmt src/lapacke-sys.rs
```
