Hi , I have problem with making for loop
I have 01~12 files and contain adt. I going to mean each month of adt and mean 1~12, annual adt
Here is my code and please advise any idea
myFolder='C:\Users\yki\2000\01';
filepattern=fullfile(myFolder,'*.nc');
filelist=dir(filepattern);
nFiles=length(filelist);
for i=1:nFiles
filename1= fullfile(filelist(i).folder,filelist(i).name);
ncdisp(filename1);
adt1=ncread(filename1,'adt');
end
adt1=mean(adt1,nFiles);
myFolder='C:\Users\yki\2000\02';
filepattern=fullfile(myFolder,'*.nc');
filelist=dir(filepattern);
nFiles=length(filelist);
for i=1:nFiles
filename2= fullfile(filelist(i).folder,filelist(i).name);
ncdisp(filename2);
adt2=ncread(filename2,'adt');
end
adt2=mean(adt2,nFiles);
myFolder='C:\Users\yki\2000\03';
filepattern=fullfile(myFolder,'*.nc');
filelist=dir(filepattern);
nFiles=length(filelist);
for i=1:nFiles
filename3= fullfile(filelist(i).folder,filelist(i).name);
ncdisp(filename3);
adt3=ncread(filename3,'adt');
end
adt3=mean(adt3,nFiles);
myFolder='C:\Users\yki\2000\04';
filepattern=fullfile(myFolder,'*.nc');
filelist=dir(filepattern);
nFiles=length(filelist);
for i=1:nFiles
filename4= fullfile(filelist(i).folder,filelist(i).name);
ncdisp(filename4);
adt4=ncread(filename4,'adt');
end
adt4=mean(adt4,nFiles);

I answered this in your duplicate question. You need to sum up the output of ncread() into a variable, then after the loop divide the sum by the number of files.
