17. iruby notebook

18. Browser based Ruby REPL for interactive computing.

19. Runs in your browser Input cell – accepts Ruby code

    Output cell – can render HTML/CSS/JS
20. None

21. nmatrix

22. n­dimensional array object. Interface Ruby with high speed C libraries.

23. require 'nmatrix' n = NMatrix.new( [2,2], [1,2,3,4], dtype: :float32, stype:

    :dense ) n[0,1] # => 2.0

24. Data Types :int8 :float32 :int16 :float64 :int32 :complex64 :int64 :complex128

25. 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.

26. NMatrix C API

28. nmatrix is coming to jruby!

29. nyaplot

30. interactive plotting tool for Rubyists.

31. interactive HTML and JavaScript plots that can be displayed in

    your browser.
32. None

33. Mapnya Nyaplot3D Bionya Map visualizations with inbuilt country charts. Three

    Dimensional interactive plots. Biology plots for visualizing relationships of genes.

34. daru (Data Analysis in RUby)

35. daru == (Hindi) ददार

36. library for analysis, cleaning, manipulation and visualization of data.

37. Read/write many data sources Ephemeral statistics functions Works well with

    'wild' data Data indexing

38. Acts as glue between other SciRuby libraries.

39. Daru::Vector Heterogenous Array that can be indexed on any Ruby

    object. Name Label(0) Label(1) Label(2) ... Label(n-1)

40. 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) ....
