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 a successor to Ruby/NArray.

under development

• Numo::Linalg - Linear Algebra library with LAPACK.
• Numo::GSL - Ruby interface for GSL (GNU Scientific Library).
• Numo::FFTE - Ruby interface for FFTE (A Fast Fourier Transform library with radix-2,3,5).
• Numo::Gnuplot - Simple and easy-to-use Gnuplot interface.

apt install -y git ruby gcc ruby-dev rake make
git clone git://github.com/ruby-numo/narray
cd narray
gem build numo-narray.gemspec
gem install numo-narray-0.9.0.3.gem

An example

[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
