Octave is a programming environment that makes it easier to prototype machine learning algorithms. The open-source software is free to download making it a nice alternative to MatLab. This is not meant to replace your production-ready Java, Python or C++, it's simply designed to help you test out your idea or intuition without having to write lots of code.
If you'd prefer to just download the app instead of using Homebrew, download Octave here.
