I've developed some boost::python code that allows conversion from numpy
arrays to boost::multi_array_refs and from boost::multi_array(ref)s to
numpy arrays without copying data. It does not deal with lifetime
management but nevertheless I've found it very useful. I know pyublas
performs a similar function including lifetime management but that is
restricted to matrices and vectors. So if anyone is interested I'd be
very happy to share it.
It does already handle both C and fortran ordered storage and I have in
mind to extend it to deal with slices, strides, etc... but have not
needed this yet.
John.
