Store and use iterations from for loop

i=1;
finish = size(A,3);
for i = 1:1:finish
  RMSE(A(:,:,i),Exp);
end

I have a 3D array (database) called A. This array consists of rows x columns x pages. Each page represent a different set of rows x columns. I want to calculate RMSE for each "page" of A with respect to the experimental results. I want to somehow store all the iterations from the for loop in a separate array (call it M), so then I can find the minimum of M and use it elsewhere. Any ideas?

Dimensions of Exp?

Perhaps like this?

finish = size(A,3);
result = zeros(1, finish);
for i = 1:finish
  result(i) = RMSE(A(:,:,i), Exp);
end

Or is the "RMSE" part the problem?
