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.

maxrating = 3;
AAADowngrade = cell(maxrating,1);
l=10; %end rating
for rating = 1 : maxrating
k = rating+1; %start rating
thisAAADowngrade = zeros(100,l-k+1);
for i=1:100
for j=k:l
thisAAADowngrade(i,j-k+1) = sum(tHistorical(rating,j:l,i));
end
end
AAADowngrade{rating} = thisAAADowngrade;
end
You need a cell array because the arrays are not all the same size.
