Ruby Library #12

Closed ankane closed 4 years ago

ankane commented 4 years ago

Hi David, I came across your work last week and am a big fan of a number of your projects!

I wanted to let you know I created a Ruby library for IsoTree. It's fairly basic right now (only supports numeric data and has a limited number of methods and options) and follows the Python API. If you have any feedback, let me know or feel free to create an issue on the project. Thanks!

Great, thanks! I'll add a link in the readme.

I unfortunately don't know ruby and would have no clue about how to test it, so cannot provide any feedback. Only would like to ask if the Numo::Narray that you are using there uses or casts the input data to column-major order, as it seems to closely follow numpy's design which by default uses row-major order.

Thanks @david-cortes, I missed that. I've added more tests to make sure the output matches exactly. Thanks for adding it to the readme!
