Solve differentianl equations in pure Ruby

Spitzy

Spitzy is this cute pomeranian. Spitzy reads backwards as yztips, which translates into:

Your Zappy-Tappy Initial and boundary value Partial (and ordinary) differential equation Solver

Now, spitzy is also a small collection of numerical methods for differential equations, written in Ruby.

Installation

Stable

Add this line to your application's Gemfile:

gem 'spitzy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install spitzy

Development

spitzy can be installed using the command line (or something similar):

git clone https://github.com/agisga/spitzy.git
cd spitzy/
bundle install
bundle exec rake install

The automatic tests can be executed with bundle exec rspec spec.
