Again, the distributed docs do *not* describe the actual
behavior for the non-unique case. E.g.,
>>> np.intersect1d([1,1,2,3,3,4], [1,4])
array([1, 1, 3, 4])
Might this is a better example of
failure than the one in the doc editor?
However the doc editor version states that the function
fails for the non-unique case, so it seems there was a
documentation bug that is in the process of being fixed.
Thanks,
