[Numpy-discussion] User-defined data-types

Hi, We need to make a dtype that needs to be defined in the user's application space. In the NumPy book there is a section devoted to this subject, but also warns: """ Adding data-types is one of the less well-tested areas for NumPy 1.0, so there may be bugs remaining in the approach. """ Anybody out there has tried this successfully? Thanks, -- Francesc Alted
