[IPOL discuss] Best Practices for Scientific Computing

[Pierre Moulon]

High Level language help to make a code that look similar to the basis
algorithm.
Less instruction make the code clear and readable and so easier to modify
by an external user.

But using some libraries in C++ help to make code more 'high-level'.
Using libs like Eigen for math do not make using pointer for matrices
manipulation... Encapsulation, objects, and concepts are keys to realize a
cool looking clean. But hard to design sometimes...

Interesting to read:
http://en.wikipedia.org/wiki/High-level_programming_language

And for me C++ is already a High-Level language.
It offer high level programming option (concepts, traits, C++11: functors,
lambda), but if you want you can go to the deep/dark side (intrinsic,
pointer arithmetic...).
