So it's 1.0 ?

Indeed. Looks like the default axis changed from 0 in 1.0 to None in the incoming 1.2. But that's a detail at this point. > > Anyway: you should use ma.median for masked arrays.

The method mean has always been around for masked arrays, so has the corresponding function. But I'm surprised, median has been in numpy.ma.extras for a while. Maybe not 1.0... > According to this page: > > http://www.scipy.org/Download > > 1.1.0 is the latest release. You need to update your internet ;) 1.1.1 was released 6 weeks ago. > Do I need to use an SVN build to get the > ma.median functionality? No, you can install 1.1.1, that should work. Note that I just fixed a bug in median in SVN (it would fail when trying to get the median of a 2D array with axis=1), so you may want to check this one instead if you feel like it. You can still use 1.1.1 : as a quick workaround the forementioned bug, use ma.median(a.T, axis=0) instead of ma.median(a,axis=1) when working w/ 2D arrays. _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
