I'm missing name spaces in matlab. everything is
from path import *

and it's more difficult to keep are larger project organized in matlab
than in python.

But, I think,
matlab is ahead in parallelization (which I haven't used much)
and learning matlab is easier than numpy. (dtypes and broadcasting are
more restrictive in matlab but, for a beginner, easier to figure out)
