Numo::NArray - New NArray class library for Ruby/Numo (NUmerical MOdule)
Numo::NArray is an Numerical N-dimensional Array class for fast processing and easy manipulation of multi-dimensional numerical data, similar to numpy.ndaray. This project is the successor to Ruby/NArray.

Installation
Requirement
Ruby ver 2.2 and later.
Ubuntu, Debian, Bash on Windows
shell
apt install -y git ruby gcc ruby-dev rake make
gem install specific_install
gem specific_install https://github.com/ruby-numo/numo-narray.git
Quick start
An example
ruby
[1] pry(main)> require "numo/narray"
=> true
[2] pry(main)> a = Numo::DFloat.new(3,5).seq
=> Numo::DFloat#shape=[3,5]
[[0, 1, 2, 3, 4],
[5, 6, 7, 8, 9],
[10, 11, 12, 13, 14]]
[3] pry(main)> a.shape
=> [3, 5]
[4] pry(main)> a.ndim
=> 2
[5] pry(main)> a.class
=> Numo::DFloat
[6] pry(main)> a.size
=> 15
