Not a surprise at all, and I should have thought about it: concatenate creates a plain ndarray first and ends up calling Unit_array.__array_finalize__. As the caller has no unit yet (it's a plain ndarray), the result gets the Unit_array.default_unit. That's why you should really write a custom concatenate function that checks the units of its inputs, and sets the unit of the output accordingly. _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
