How to take an average over one month during different years ?

16 views (last 30 days)
Hi,
I've got some data from 1979 to 2017. I want to take an average over data of month, for example, January from 1979 to 2017. Only January, not other months. PLease see attached. I have also attached my Matlab file which contains the table with date and data. If you could take a look and let me know how I can do it, I would appreciate it. Thank you.
Regards Ali

A bit hard to tell from your screenshot whether your time array is an array of datetimes or an array of date strings. Assuming it's the former
% Some fake data
t = datetime(1979,1,1):datetime('today');
x = rand(size(t));
% Average data by month
for im = 1:12
xavg(im) = mean(x(month(t)==im));
end

I don't see any attached mat file. If you post the exact code you attempted, and any error messages, that will be much more useful than screenshots to diagnose the problem.
In particular, is the Time column in your table composed of datetimes or date strings?
