Displaying the image

I have a code

A-is a matrix

n = numel(A);

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

end

I have a matrix ,where i have multipied that matriix waith those 20 genertaed matrix,now i have 20 matrix and have found error,now i want to display the image which has minimum error,please help

[kash]

A is an image its matrix size is 256x256

A1_20(:,:,j1).*p will give 20 matrices(images)

for all these 20 images i have found error

so for 20 images i will get 20 error values,in that i want to find the minimum error and display that image
