also i assume you're using a numpy / C structure for all of this
right? Also depending on the number of cores you have you could try
parallelizing all of your loops with multiprocessing / if applicable

Well I rely on the `propertymap.a` and `propertymap.fa` attributes,
which are subclasses of numpy ndarray. As for multiprocessing, of
course, but I only have 4 cores, so... As for GPU processing, I don't
know whether there is a simple way to do this in python.
I guess the real efficient way would be to dive into the underlying C++
API, but I am not very C++ litterate and look for something simpler.
But avoiding the inelegant loop over all edges is already interesting...
Thanks for the suggestion anyway!

Hi Tiago,
Thanks for the blazing fast answer!
It will sure do the job. I can't find it in the documentation though (it's
accessible online via ipython autocompletion and magic '?', but doesn't appear
on your web site).
Oops... Indeed. I'll add it in the next release.
Cheers,
Tiago

Ok cool..
One more point:
Is there a way to do the following differently:
edge_x = g.new_edge_property()
edge_x.a = np.array([x[e.source()] for e in g.edges()])
with x being a vector property map.
I plain English, is there a (more efficient) way to copy the
vertex property map of every edge source to an edge property map?
