[Numpy-discussion] unique along axis?

[Neal Becker]

I see unique does not take an axis arg.

Suggested way to apply unique to each column of a 2d array?

A for-loop?

I'm guessing that there isn't an axis keyword because the number of unique elements per column may not be the same, so you can't return an ndarray.
