So the underlying problem here is that each array has a (widely different) size? > cdef np.ndarray w[30] No, it will be a long while before you can do this. Perhaps in a year one /might/ be able to use e.g. a C++ vector of buffers, but no promises. You can always wrap the solution above into e.g. a cdef class, so that you can write yourspecialarrayobject.get(k, i, j) -- Dag Sverre _______________________________________________ Cython-dev mailing list [email protected] http://codespeak.net/mailman/listinfo/cython-dev
