Note that in both suggest approaches, sort with NaN would raise an error. We could then provide a nansort, which ignore the NaN, and deal with your case; would it be hard to have an option for the beginning vs the end, or would that be difficult ? cheers, David _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
