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
