## Description

Ruby/GSL is a ruby interface to the GNU Scientific Library (GSL), for numerical computing with Ruby.

## Installation

### Using the gem command

Ruby/GSL may now be installed as a Ruby Gem by simply running

    gem install gsl

Note that the GSL libraries must already be installed before Ruby/GSL can be installed.

### Using the setup.rb command

If you prefer, Ruby/GSL may still be installed using setup.rb.

1. Get and install GSL. Make sure the command "gsl-config" is in command search path.

2. Download Ruby/GSL, ungzip and untar the archive `rb-gsl-xxx.tgz`.

3. `% cd rb-gsl-xxx/`

4. `% ruby setup.rb config`

5. `% ruby setup.rb setup`

6. `% ruby setup.rb install` (as root)

- It is recommended to install the GNU plotutils package. Some of the example scripts in the 'examples/' directory use the `graph` utility included in the package to plot the results. Windows-cygwin binaries of `GNU plotutils` and related packages are available from here.

## Screenshot

Ruby/GSL can be seen in action in these screenshots.

## Reference

The Ruby/GSL reference manual follows and borrows large parts of the GSL reference manual.

## Examples

See scripts in `examples/` and `tests/` directories.
