Numo::NArray Alternative

Numo::NArray Alternative is an experimental project forked from Numo::NArray. Its goal is to adopt more modern Ruby features and development practices. The project owner is also the developer of Rumale, a machine learning library, and may add new features to this project to support the needs of Rumale. In addition, since Rumale depends on Numo::NArray, namespaces, class names, and method names will be kept unchanged to allow this library to be used as a drop-in replacement.

The project owner has the utmost respect for Numo::NArray and its creator, Prof. Masahiro Tanaka. This project is in no way intended to adversely affect the development of the original Numo::NArray.

$ gem install numo-narray-alt

The same as Numo::NArray.

irb(main):001> require 'numo/narray'
=> true
irb(main):002> x = Numo::DFloat[[1, 2, 3], [4, 5, 6]]
=>
Numo::DFloat#shape=[2,3]
...
irb(main):003> x.dot(x.transpose)
=>
Numo::DFloat#shape=[2,2]
[[14, 32],
 [32, 77]]
