GNU Scientific Library (GSL) binding for Crystal

## Installation

Add this to your application's `shard.yml`:

```yaml

dependencies:

  gsl:

    github: konovod/crystal-gsl

```

Run `shards install`

## System dependencies

### Ubuntu

- libatlas-base-dev

- libgsl-dev

### Fedora

- gsl

- gsl-devel

### MacOS

- brew install gsl

### Windows

 - Recommended on [GSL website](https://www.gnu.org/software/gsl/extras/native_win_builds.html) way to get GSL on Windows is to build manually using .sln files from https://github.com/BrianGladman/gsl

## Usage

```crystal

require "gsl"

```

### Documentation

(Incomplete) documentation can be found [here](https://konovod.github.io/crystal-gsl/). It is generated from sources, so can be messy.

You can also check original GSL docs for details of implementation and theory (https://www.gnu.org/software/gsl/doc/html/)

### Examples

You can check `spec` directory for some simple examples

_Warning_:

- Mostly tested, but some bugs are possible

- Pre-release (API could break)

- Perhaps not ready for production

## Status

If you know GSL, you can call all GSL functions directly: `LibGSL.gsl_some_function(arg, ...)`. This could be cumbersome, but it works.

For a high-level wrappers, see [TODO.md](https://github.com/konovod/crystal-gsl/blob/master/TODO.md) for detailed list on what is done\missing.
