In the cases broadcasting is expensive memory wise, ctypes is really a
good option, too, specially for basic numerical works done in a few
lines of C (typically, you allocate your data in python with
numpy.empty, and gives those arrays to C functions).
Concerning memory usage, I have just discovered a fantastic tool for
memory usage: massif. It is part of valgrind, and it gives you this kind
Your scripts will run extremely slowly (10-20x slower), but it is
extremely useful, at least for me.
