Matrix Version Bundled Gem Test

An implementation of Matrix and Vector classes.

The Matrix class represents a mathematical matrix. It provides methods for creating matrices, operating on them arithmetically and algebraically, and determining their mathematical properties (trace, rank, inverse, determinant, eigensystem, etc.).

The Vector class represents a mathematical vector, which is useful in its own right, and also constitutes a row or column of a Matrix.

Installation

The matrix library comes pre-installed with Ruby. Unless you need recent features, you can simply require 'matrix' directly, no need to install it.

If you need features that are more recent than the version of Ruby you want to support (check the CHANGELOG), you must use the gem. To do this, add this line to your application's Gemfile or gem's gemspec:

gem 'matrix'

And then execute:

$ bundle

To make sure that the gem takes precedence over the builtin library, call bundle exec ... (or call gem 'matrix' explicitly).

Usage

require 'matrix'
m = Matrix[[1, 2], [3, 4]]
m.determinant # => -2

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Contributing

Bug reports and pull requests are welcome on GitHub at https://github.com/ruby/matrix.

License

The gem is available as open source under the terms of the 2-Clause BSD License.
