ruby-alglib

• ALGLIB for Ruby.
• ALGLIB is a numerical analysis and data processing library. This repository provides bindings primarily for statistics.

Installation

From source code:

git clone https://github.com/kojix2/ruby-alglib
cd ruby-alglib
bundle install
rake ext:alglib # Download ALGLIB Free Edition from https://www.alglib.net/ and extract to ext/alglib.
rake compile
rake install

• Note that the license of ALGLIB Free Edition is GPL or Personal/Academic license.
• If you want to use ALGLIB in a commercial application, you will need to purchase a commercial license.
  • Can I use ALGLIB Free Edition in a commercial application which runs on server?
• You can also use the Commercial Edition of ALGLIB. In that case, you need to replace the files in ext/alglib with the files in the Commercial Edition.
• Windows is not supported.

Development

Not-To-Do List

• Creating namespaces under Alglib. (e.g. Alglib::Statistics)
• Trying to implement all functions even if you do not plan to use them.
• Adding features that will require frequent maintenance.
• Enforcing the above policies on forked repos.

Rice - C++ binding

We use Rice to create Ruby's C++ binding.

License

• ruby-alglib itself (the code in this repository) is distributed under the MIT license.
• However, ALGLIB for C++ Free Edition is under the GPL 2+ license.
• The algblib4 gem distributed with the RubyGem server is GPL 2+ licensed because it contains ALGLIB for C++ Free Edition code.
• Please read FAQ carefully before you use ALGLIB to understand what is allowed in the free version.
  • Can I use ALGLIB Free Edition in a commercial application which runs on server?

    You can, but there is at least one reason to buy commercial license. Everything is OK while it is just running on your server. But any action connected with distribution - selling, sublicensing, transferring to someone under nondisclosure agreement - will trigger copyleft clause. So it is safer and more convenient to buy commercial license.

• Theoretically, ruby-alglib should work with the commercial version. That is why it is MIT. But we have not verified this.
