A while ago I wrote a mex extension to embed the Python interpreter
inside Matlab:

I guess it's something like an inverse of pymat :)

But I guess this is not really what you are looking for, since at
present it just does a memory copy when passing arrays between Matlab
and Python. Though, shared arrays might be just possible to implement if
memory management is done carefully.
