how to make hourly, daily monthly rainfall in matlab?

2 views (last 30 days)
Dear colleagues I have excel file to show rainfall in each minute. I would have rainfall in hourly, daily and monthly. It means that i need to sum each hour to show hourly (cumulative). and sum each day to show daily and each month for showing monthly rainfall (cumulative). I read some codes from internet but i cant run them. I am new in matlab and I need to do this job. I attached the excel file as small sample but my data are growing each day.

data = xlsread('rain.xlsx');
[y,mm,d,h,m] = datevec(data(:,1) + datenum([1900 0 0]) - 1);
cum_minutes = [y,mm,d,h,m, cumsum(m)];
[hy,~,hc] = unique([y,mm,d,h],'rows');
cum_hourly = [hy, cumsum(accumarray(hc,data(:,2)))];
[dy,~,dc] = unique([y,mm,d],'rows');
cum_daily = [dy, cumsum(accumarray(dc,data(:,2)))];
[mhy,~,mhc] = unique([y,mm],'rows');
cum_monthly = [mhy, cumsum(accumarray(mhc,data(:,2)))];
