Thank you very much Daniel! I had another question, is it possible to use multi_array and const_multi_array_ref together in python. What I mean is, if I create a multi_array from python through my c++ functions and I want to pass this array to another c++ function that uses a const_multi_array_ref how do I manage this in the interface file? is this possible? I added class_<const_multi_array_ref<double, 2>
("const_multi_array_2d_ref"); to my interface file but the types seem to be incompatible. I would prefer to use the const_multi_array_ref with the multi_arrays to avoid copies...
I had to rewrite my functions to use only multi_array's to make the code I had attached work. Daniel Wallin wrote:

So you see I can't use my code, what am I doing wrong?
You didn't export multi_array<double, 2> to Python. If you just want to pass the multi_array's around without manipulating them, it's enough to export it without any functions:
class_<multi_array<double, 2> >("multi_array_2d");
If you want a more complete binding, there's binding code for boost::multi_array queued for inclusion on the CVS. It's currently on a branch:
