[Torch5-devel] torch5 newbie question

[Mikaela K. <mik...@gm...>]

Hi,
I suppose this is (will be) a very common question... Lets have it
documented.
How do you decide whether a class should be a C++ class or a Lua class?
Or why do you have for example in the nn package a 
StochasticGradient.lua instead of a StochasticGradient.cpp? And in the 
lab package you have a matelem.cpp AND a matelem.lua!?
Thanks,
Mika
