I'm aware that there exist machinery in scipy to read matlab files
(see io.loadmat). However, I think that this format it is not meant to
become a standard (although it might become a 'de facto' standard, a
la Microsoft Office), and in fact, MathWorks does change the format
from time to time to accomodate more features.
Contrarily, HDF5 is designed to be an standard, and the people behind
it tries hard to ensure not only backward compatibility, but also
forward compatibility (to the extend that this is reasonably
