Hi
I have time series. I want to stack monthly(hist). I need to count how many times my time series repeated in every month for given long period and stack each month results. January+January, February+February, March+March..... Such as January would be repeated 250, February 300, March 280.......
(Please see attached excel file).
Thanks a lot!

[~,~,c] = xlsread('stack_monthly.xlsx');
[y,m] = datevec(c,'yyyy-mm-ddTHH:MM:SS.FFFZ');
a = unique([y,m],'rows');
out = accumarray(a(:,2),1);

[d,~,c] = xlsread('stack_montlyvalues.xlsx');
[~,m] = datevec(c(:,1),'yyyy-mm-ddTHH:MM:SS.FFFZ');
[a,~,ii] = unique(m);
out = [a,accumarray(ii,d)];
