Hi all,
I want to extract data based on the months using this function 'monthofyear' to calculate anomalies.
The written code shows the wrong results.
Any help is appreciated
anom=[];
i=1;
for yy = 2019
ndays = eomday(yy, 1:12);
for mm = 1:12
for dd = 1:ndays(mm)
monthofy = month(datetime(yy,mm,dd),'monthofyear');
nn = norm(:,:,monthofy);
anom(:,:,i) = sez_chl - nn; %sez_chl is 3d matrix 72*46*46
i=i+1;
end
end
end

There is a whole family of "outlier" functions, like rmoutliers(), etc. Look into them.

Note that you forgot to read this
and attach your data, so all we can do is guess. We have not seen your time series data, sez_chl, or norm.
