Hi,

I just read a paper[1] that compare python with numpy or pypy vs c++ and fortran from a code, memory and speed point of view. The python code was still better as you can't have list of ndarray in fortran and some other stuff was harder to do. The fastest was fortran, then C++, but pypy around 2x slower then c++. That isn't bad for a more productive development language.

Maybe you can check that article to find more case to compare.

Hi,

I have recently setup a page about modern Fortran:

and in particular, it has a long section with side by side syntax examples of Python/NumPy vs Fortran:

http://fortran90.org/src/rosetta.html

I would be very interested if some NumPy gurus would provide me feedback. I personally knew NumPy long before I learned Fortran, and I was amazed that the modern Fortran pretty much allows 1:1 syntax with NumPy, including most of all the fancy indexing etc.

Is there some NumPy feature that is not covered there? I would like it to be a nice resource for people who know NumPy to feel like at home with Fortran, and vice versa. I personally use both every day (Fortran a bit more than NumPy).

Or of you have any other comments or tips for the site, please let me know. Eventually I'd like to also put there C++ way of doing the same things, but at the moment I want to get Fortran and Python/NumPy done first.
