Problem with the looping

tr(i,j,ni) is 361*361*432 

ind=10:16; % Winter average over month Oct to following year's April
  for k=1:(ni/12)-1
      meanr = nanmean(tr(i,j,ind));
      tmeanr(i,j,k) = meanr;
      ind = ind  + 12;
  end

The values in  * *meanr* = nanmean(tr(i,j,ind));* are showing all zeros.

ind values showing are 430-436, but since i don't have the complete winter data values for 2014(i just have oct to dec for 2014 not jan to apr 2015), so i want this ind to show 418-424 instead.

Use an "if" to check for that value and if the value is in the "missing" range then either "continue" or subtract 12 from ind to get it into the range you want.

Or else insert data for the "missing" months, like zeros or something, so that it will have something there in the right spot.

I tried this, and it works,But the means still show zeros

t_r = zeros(361,361,35);
ind=10:16;
for t=1:(ni/12)-1;
    if t<=34
        wint_tr = nanmean(tr(i,j,ind));
        t_r(i,j,t) = wint_tr;
        ind = ind  + 12;
    else
    end
end
* *mean_winter_sid = mean(t_r,3);** all values in this are showing zero
