Hi all, There is a PR, ready to be merged, that adds the possibility of passing a tuple of arrays in the 'out' kwarg to ufuncs with multiple outputs:
https://github.com/numpy/numpy/pull/5621 The new functionality is as follows: * If the ufunc has a single output, then the 'out' kwarg can either be a single array (or None) like today, or a tuple holding a single array (or None). * If the ufunc has more than one output, then the 'out' kwarg must be a tuple with one array (or None) per output argument. The old behavior, where only the first output could be specified, is now deprecated, will raise a deprecation warning, and potentially be changed to an error in the future. * In both cases, positional and keyword output arguments are incompatible. This has been made a little more strict, as the following is valid in <= 1.9.x but will now raise an error: np.add(2, 2, None, out=arr) There seemed to be a reasonable amount of agreement on the goodness of this change from the discussions on github, but I wanted to inform the larger audience, in case there are any addressable concerns.
