Numo::NArray is an Numerical N-dimensional Array classfor fast processing and easy manipulation of multi-dimensional numerical data,similar to numpy.ndarray.This project is the successor toRuby/NArray.

All documents are primitive.

• Numo::FFTW - Ruby/Numo interface toFFTW (A Discrete Fourier Transform library.
• Numo::FFTE - Ruby interface forFFTE (A Fast Fourier Transform library with radix-2,3,5).
• Numo::Gnuplot - Simple and easy-to-use Gnuplot interface.

Ruby ver 2.2 and later.

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

For more examples, check out thenarray version of 100 numpy exercises.

• Wiki version of the 100 exercises
• Reproducible version of the 100 exercises (With this, you can try narray without creating an environment locally.)
