[GSoC|D3] NMatrix method equal to Numpy.meshgrid

[Naoki Nishida]

Hi All,

I am now expanding Ruby front-end of my GSoC project and trying to integrate it with other SciRuby components. Then I have a question about NMatrix.

I would like to use methods like Numpy.meshgrid[0] in Ruby. It do not do so complex things, but it is convenient when we generate plots like vector field[1] or 3D plot[2].

I read documents of NMatrix, but I cannot find the word 'meshgrid' in it. Does it already have methods equal to Numpy.meshgrid?

Regards,

Naoki

Hi Naoki,

We don't have a NMatrix#meshgrid function, but it should be similar to the NMatrix#linspace (and #logspace) shortcuts, which can be found in:

https://github.com/SciRuby/nmatrix/blob/master/lib/nmatrix/shortcuts.rb#L596-L606

If anyone is interested in writing NMatrix#meshgrid, feel free to send a pull request. :)

Hi Carlos,

Thank you for your reply. 

I tried to implement NMatrix#meshgrid, but I cannot finish it because of my lack of knowledge on NMatrix.

There is unfinished code on GitHub, and could you look over it if you have time?
