How to store <500x500> double in a loop?

I have following loop,

for e=1:25                               
:
:
:
finalLSF(e)=phi; % phi is where 500x500 double

end

How to store 500x500 double in a loop I have tried finalLSF(e) and finalLSF{e}, but it gives me an errors:

In an assignment  A(I) = B, the number of elements in B and I must be the same.

and

Cell contents assignment to a non-cell array object.

How it is can be done properly in matlab?

finalSF{e} should work. If you're getting an error, it's probably because finalSF already exists before the loop as something else than a cell array. To fix that:

finalSF = cell(1, 25); %before the loop.

Another option is to declare finalSF as a 3d array, since all your phi are the same size:

finalSF = zeros(500, 500, 25);
for idx = 1:25
   %calculate phi
   finalSF(:, :, e) = phi;
end
