i am trying to loop through three variables and store the data from each loop:

    for rating=1:3
   k=rating+1;  %start rating
      l=10;     %end rating
   AAADowngrade=zeros(100,l-k+1,rating);
     for i=1:100
         for j=k:l
   AAADowngrade(i,j-k+1,rating) = sum(tHistorical(rating,j:l,i));
           end  
     end
    end

However, the code above only stores data from the final rating (rating =3). The first two tables just have zeros in them.
