Numo::NArray is an Numerical N-dimensional Array class
for fast processing and easy manipulation of multi-dimensional numerical data,
similar to numpy.ndarray.
This project is the successor to [Ruby/NArray](http://masa16.github.io/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
```
For more examples, check out the **narray version of 100 numpy exercises**.
- [Wiki version](https://github.com/ruby-numo/numo-narray/wiki/100-narray-exercises) of the 100 exercises
- [Reproducible version](https://mybinder.org/v2/gh/ruby-numo/numo-narray/HEAD?filepath=100-narray-exercises.ipynb) of the 100 exercises (With this, you can try narray without creating an environment locally.)
## Development
### Build
```shell
git clone https://github.com/ruby-numo/numo-narray
cd numo-narray
bundle install
bundle exec rake compile
```
### Run tests
```shell
bundle exec rake test
```
Tips: You may run tests defined in a specified line as:
```shell
bundle exec ruby test/bit_test.rb --location 27
```
