This reminds me of a function [1] I wrote which I think has a lot of similarities to what Stephan describes here. It is currently part of a PR to rewrite numpy.pad [2]. Maybe that's helpful to know depending on how this discussion resolves. :) Best regards, Lars [1] https://github.com/lagru/numpy/blob/605fc1d7f871b1c8cf2783f594dee88cdf96d7ec/numpy/lib/arraypad.py#L14-L67 [2] https://github.com/numpy/numpy/pull/11358 _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@python.org https://mail.python.org/mailman/listinfo/numpy-discussion
