I am given a large group of data that involves months and years and was looking for a quick way to process this. It is easiest to do this using two for loops but I need to retain that information. I have tried using {} but that will only let me use one of the loops. So far, my code is:

 for mo=1:12
   for year=2005:2015
     [dttm,timemin,wnddatenum,wndspeed,wnddir,pres,temp]= ...
                         RdNCDCData(filename,mo,yr,iminsamp);
   end
 end

How would I be able to get an array giving the month and year as something like [1,2005] for the variable?

在 MATLAB Online 中打开

 yearno = 2005:2015;
 for mo = 1:12
   for yearidx = 1 : length(yearno)
     year = yearno(yearidx);
     [dttm{mo,yearidx}, timemin{mo,yearidx}, wnddatenum{mo,yearidx}, wndspeed{mo,yearidx}, wnddir{mo,yearidx}, pres{mo,yearidx}, temp{mo,yearidx}] = RdNCDCData(filename, mo, year, iminsamp);
   end
 end
