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:

http://fortran90.org/

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.
