MATLAB: Error in storing values

matri

I have a code
for xx = 1:length(dirlist(1:2))
    x = imread([pathname, dirlist(xx).name]);  
x=rgb2gray(x);
x=double(x);
   n = numel(x);
  A1_20 = repmat(A,[1,1,20]);
  t = ones(size(A));
  for j1 = 1:size(A1_20,3)
      p = t;
      p(randi(n,3000,1)) = 0;
      A1_20(:,:,j1) = A1_20(:,:,j1).*p;
       w{j}{s1}{s2} =A1_20(:,:,j1);
    y1 = idualtree2D(w, J, Fsf, sf);
     Er= mean2((single(x) - single(y1)).^2);
    final_col2{xx}=min(Er)
  %   figure,imshow(uint8(y1))
     Er1= mean2((single(x) - single(y1)).^2)/20;
     Mse{j1}=Er1
  end
    end
              end
  end  
  end
i have taken two images,Mse{j1} stores error for only second image,i want even for 1st image to be stored,the second image error values is overwriting the first ,please help how to store both

I haven't looked in detail, but it looks like the variable xx counts over your images? So, if you replace this line
Mse{j1}=Er1
with this
Mse{xx,j1}=Er1
do you get everything you want stored in Mse?
