crystal-gsl

GNU Scientific Library (GSL) binding for Crystal

Installation

Add this to your application's shard.yml:

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 way to get GSL on Windows is to build manually using .sln files from https://github.com/BrianGladman/gsl

Usage

require "gsl"

Documentation

(Incomplete) documentation can be found here. 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.
