[Octave-bug-tracker] [bug #48774] Functions for moving statistics

[Rik]

Follow-up Comment #28, bug #48774 (project octave):

@Juan: Regarding 'omitnan', it does not appear to be implemented so I added a
warning.  Here is test code that I used.


x = (1:10)';
x(5) = NaN;
movmean (x, 3, 'omitnan')


Under Matlab, this produces


ans =

   1.5000
   2.0000
   3.0000
   3.5000
   5.0000
   6.5000
   7.0000
   8.0000
   9.0000
   9.5000


Using the original implementation from your repository


octave:8> movfun (@mean, x, 3, 'nancond', 'omitnan')
ans =

   1.5000
   2.0000
   3.0000
      NaN
      NaN
      NaN
   7.0000
   8.0000
   9.0000
   9.5000



For completeness, running with 'includenan' in Matlab


movmean (x, 3, 'includenan')
ans =

   1.5000
   2.0000
   3.0000
      NaN
      NaN
      NaN
   7.0000
   8.0000
   9.0000
   9.5000
