I want to save the data in for loop but it only gives me the last data. How can I accumulate the data in row?
----------------------------
Month ={'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'};
m=[];
for year = 2000:2001
for month = 1:12
m=sprintf('%04d%s', year, Month{month});
end
end

m is a cell array indicated by { }
help cell
if m=[ 1 2 5] then m(end)=5,
when you type m(end+1) it means m(3+1)
