Probably a good idea, since in the current NEP, masks do not have a 'where' clause effect (at least for reduction operations), unless you pass skipna=True. So calling it mask= would be a bit confusing :-) So if I understand right, f(a, b, where=c) is basically an optimized (copy-avoiding) version of f(a[c], b[c]) ? Except, in this case, c must be a boolean array of exactly the right shape, you don't support broadcasting or integer arrays or slices, etc.? -- Nathaniel _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
