Details:

octave:6> which median
`median' is a function from the file
/usr/local/share/octave/3.3.51+/m/statistics/base/median.m
octave:7> median([1,2,3,NaN,NaN])
ans =  3


The result should be either NaN (this is the result of ML), or it should be 2
(like the NaN-toolbox, considering NaN's as missing values).
