9. nmatrix @srijan #SrijanWW

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

    @srijan #SrijanWW

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

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

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

    @srijan #SrijanWW

13. 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. @srijan #SrijanWW

14. NMatrix C API @srijan #SrijanWW

15. nmatrix nmatrix­ atlas nmatrix­ lapacke nmatrix­ fftw gsl @srijan #SrijanWW

16. nmatrix is coming to jruby! @srijan #SrijanWW

17. nyaplot @srijan #SrijanWW

18. interactive plotting tool for Rubyists. @srijan #SrijanWW

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

    your browser. @srijan #SrijanWW

20. @srijan #SrijanWW

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

    Dimensional interactive plots. Biology plots for visualizing relationships of genes. @srijan #SrijanWW

22. gnuplotrb @srijan #SrijanWW

23. Ruby wrapper over GNU Plot. Convieniently exposes all GNU Plot

    functions through Ruby. @srijan #SrijanWW

24. require 'gnuplotrb' plot = GnuplotRB::Plot.new( [ [1,2.5,1.5,4], with: 'linespoints' ]

    ) @srijan #SrijanWW

25. @srijan #SrijanWW

26. require 'gnuplotrb' plot = GnuplotRB::Plot.new( [ [1,2.5,1.5,4], with: 'linespoints' ],

    [ [2,3,4.3,3], with: 'lines' ] ) @srijan #SrijanWW

27. @srijan #SrijanWW

28. statsample @srijan #SrijanWW

29. @srijan #SrijanWW library for statistical analysis and modelling.

30. @srijan #SrijanWW Extensions for Generalized Linear Models and TimeSeries apart

    from statistical tests and models.

31. daru (Data Analysis in RUby) @srijan #SrijanWW

32. daru == (Hindi) ददार @srijan #SrijanWW

33. library for analysis, cleaning, manipulation and visualization of data. @srijan

    #SrijanWW

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

    'wild' data Data indexing @srijan #SrijanWW

35. Acts as glue between other SciRuby libraries. @srijan #SrijanWW

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

    object. Name Label(0) Label(1) Label(2) ... Label(n-1) @srijan #SrijanWW

37. 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) .... @srijan #SrijanWW
