Francesc, you're overestimating my knowledge of C... Can we stick to the Python implementation ? Here's the catch: IIUC, each individual element of a nD structured array is a void, provided the element can be accessed, ie that n>0. A 0D array cannot be indexed, so I don't know how capture the object below. The sad trick I found was to do a .reshape(1)[0], but that looks really overkill... > > The standard way (more or less) works for me: > >>>> class myvoidclass(np.void): > ... pass > ... David, what do you do w/ the __new__ of myvoidclass ? Just an empty class doesn't help me much, 'm'fraid. _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
