[C++-sig] datastructure to numpy and back

I know this was discussed quite some times, but I did find that many 
workarounds and not really a common way how to do that with Boost.Python 
... so I am a little bit confused ...

My problem: I have a class with some (big) custom C++ matrix types and I 
want to write some getters/setters for them to/from numpy arrays, where 
I want to avoid copies of the data.

So is there a common way to do this ?
(e.g. num_util from 

Or can maybe someone link me to some docu or examples which already did 
this ? (it must be quite common ...)

Many thanks for any hint,
