Re: [Numpy-discussion] Allowing broadcasting of code dimensions in generalized ufuncs

OK, I spent my Sunday morning writing a NEP. I hope this can lead to some closure... See https://github.com/numpy/numpy/pull/11297 -- Marten ___ NumPy-Discussion mailing list NumPy-Discussion@python.org https://mail.python.org/mailman/listinfo/numpy-discu

Re: [Numpy-discussion] Allowing broadcasting of code dimensions in generalized ufuncs
