how to save data in for loop?

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{end+1}=sprintf('%04d%s', year, Month{month});

Thanks!! Would you please explain me how it works? What is 'end' and {}...?

[Azzi Abdelmalek]

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)

Thanks. Then why does it accumulates the output?
