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


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.


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


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


See scripts in examples/ and tests/ directories.
