Browser based Ruby REPL for interactive computing.
Runs in your browser Input cell – accepts Ruby code Output cell – can render HTML/CSS/JS
nmatrix
n-dimensional array object. Interface Ruby with high speed C libraries.
require 'nmatrix' n = NMatrix.new( [2,2], [1,2,3,4], dtype: :float32, stype: :dense ) n[0,1] # => 2.0
Data Types :int8 :float32 :int16 :float64 :int32 :complex64 :int64 :complex128
Storage types Dense Dense matrix. List Sparse matrix type storing data as a linked list. Yale Sparse type storing data in the 'New Yale' format.
NMatrix C API

nmatrix is coming to jruby!
nyaplot
interactive plotting tool for Rubyists.
interactive HTML and JavaScript plots that can be displayed in your browser.
Mapnya Nyaplot3D Bionya Map visualizations with inbuilt country charts. Three Dimensional interactive plots. Biology plots for visualizing relationships of genes.
gnuplotrb
Ruby wrapper over GNU Plot. Convieniently exposes all GNU Plot functions through Ruby.
require 'gnuplotrb' plot = GnuplotRB::Plot.new( [ [1,2.5,1.5,4], with: 'linespoints' ] )
require 'gnuplotrb' plot = GnuplotRB::Plot.new( [ [1,2.5,1.5,4], with: 'linespoints' ], [ [2,3,4.3,3], with: 'lines' ] )

daru (Data Analysis in RUby)
daru == (Hindi) दा
library for analysis, cleaning, manipulation and visualization of data.
Read/write many data sources Ephemeral statistics functions Works well with 'wild' data Data indexing
Acts as glue between other SciRuby libraries.
Daru::Vector Heterogenous Array that can be indexed on any Ruby object. Name Label(0) Label(1) Label(2) ... Label(n-1)
Daru::DataFrame 2D spreadsheet like data structure indexed by rows or columns. Col0 Label(0) Label(1) Label(2) ... Label(n-1) Col1 Col2 Col(n-1) ....
