both in octave core and in the statistics package, median ([NaN, NaN),
'omitnan') results in an error:


>> median([NaN NaN],'omitnan')
error: x(0): subscripts must be either integers 1 to (2^63)-1 or logicals
error: called from
    median at line 326 column 11


turns out it fails to check if all(isnan(x)) and then tries to index x for all
non-nan with x(0), triggering the error.
