I am trying to generate text files from the following example:
clear all
Year = {'2007','2008','2009'};
for i = 1:length(Year)
StartDate{i} = [Year{i} '-01-01 00:00'];
EndDate{i} = [Year{i} '-12-31 23:57'];
Resolution = 60;
DateT{i} = datestr(datenum(StartDate{i},'yyyy-mm-dd HH:MM'):Resolution/(60*24):...
datenum(EndDate{i},'yyyy-mm-dd HH:MM'),'yyyy-mm-dd HH:MM');
DateTime{i} = cellstr(DateT{i});
end
%save as text file
for i = 1:length(Year);
mkdir(fullfile('C:',Year{i}));
filename{i} = fullfile('C:',Year{i},'DateTime.txt');
fid{i} = fopen(filename{i},'w+');
for ii = 1:length(DateTime);
a{i} = 1:length(DateTime{i});
for k = 1:a{i};
fprintf(fid{i},'%s',DateTime{i}{k});
end
end
end
fclose 'all';
I know that the error must be in the line containing fprintf but I dont know how to fix it. How is it possible to write the each cell of DateTime into separate text files as indicated in the script?

I had similar problem, I used strcat after cellstr. so in this question this may work: DateTime{i} = strcat(cellstr(DateT{i}));

Replace the corresponding lines with these:
a{i} = length(DateTime{i})
for k = 1:a{i}
fprintf(fid{i},'%s\n',DateTime{i}{k});
% fprintf(1,'%s\n',DateTime{i}{k});
end
The problem was the 1: in the "a{i}" line, and no \n in the fprintf().

If you mean why it doesn't look the same when you fprintf to the file instead of the command window, it's because if you go to a file you need to use \r\n instead of just \n. I'm not really sure why that is the convention, it just is.

Using \r\n is not a convention, but text files can have either "\n" or "\r\n" or even "\r" as line breaks. Only the Windows Editor cannot display the different line breaks correctly, but e.g. Matlab's editor or any other one I've seen handles the different styles correctly. Therefore the convention should be not to use the Editor shipped with Windows.
