[Jython-users] NumJy project

[Yaqiang W. <yaq...@gm...>]

I just start NumJy project (https://github.com/Yaqiang/numjy) which is
numpy similar package for Jython. It is developed with Java + Jython. The
multiple array implemented based on the ucar.ma2 code. Apache commons math
and ejml libraries were used for scientific computation. The project was
peeled from MeteoInfo project so it can be used easily by other projects.
DataFrame, 2D/3D plot and other packages will be released in the future
which has been implemented in MeteoInfo project.

Build the project and copy numjy folder into Lib->site-packages folder of
Jython, then you can use NumJy as following.

D:\MyProgram\java\MeteoThinkDev\NumJy>jython
Jython 2.7.1 (default:0df7adb1b397, Jun 30 2017, 19:02:43)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java11.0.1
Type "help", "copyright", "credits" or "license" for more information.
>>> import numjy as np
>>> a = np.arange(10)
>>> a
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> a = a.reshape(2, 5)
>>> a
array([[0, 1, 2, 3, 4]
      [5, 6, 7, 8, 9]])
>>> a * 10
array([[0, 10, 20, 30, 40]
      [50, 60, 70, 80, 90]])
>>>

It is welcome to use and test NumJy.

Yaqiang
