Numo::NArray Alternative

Numo::NArray Alternative (numo-narray-alt) is a project forked from Numo::NArray. The project aims to support the latest Ruby features, release bug fixes as quickly as possible, and adopt modern development practices. In addition, module names, class names, and method names remain unchanged for compatibility, making it a drop-in replacement. The project owner is also the developer of Rumale, a machine learning library, and may add new features to numo-narray-alt to support the needs of Rumale.

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 usage is exactly 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]]
irb(main):004>
