[Numpy-discussion] Adding out to bincount

There is an ongoing discussion on #9397 about adding an out= keyword argument to np.bincount(). Presently the design seems headed toward: - the new counts will be added to the contents of out, perhaps we need a better name than out, suggestions

I will not be joining you for this sprint, but will be in the Bay Area from May 12th to May 25th, and wouldn't mind spending a day visiting you. If it works for you and anyone else want to join we could try to give it a little more structure than "just came over to say hi!" Jaime On Thu, Mar

Re: [Numpy-discussion] best way of speeding up a filtering-like algorithm

Hi Catherine, One problem with sliding window algorithms is that the straightforward approach can be very inefficient. Ideally you would want to not recompute your windowed quantity from all points in the window, but to reuse the result from an overlapping window and only take into account the
