from numpy import ctypeslib r = ctypeslib.as_array(x._type_ * n) If that doesn't work, then you can create an array from an arbitrary buffer or any object that exposes the __array_interface__ attribute. So, if you can get the address of c_double then you can use it as the data for the ndarray. Ask if you need more help. -Travis _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
