Displaying Image having minimum Mse

I am performing dualtree3D,i have a code for this

x=rand(256,256,10);
x=double(x);
J=1;
[Faf, Fsf] = FSfarras;
 [af, sf] = dualfilt1;
w = dualtree3D(x, J, Faf, af);

now i have created 10matrices and have multiplied w with those matrices

n = numel(A);
A1_10 = repmat(A,[1,1,1,10]);
t = ones(size(A));
for j1 = 1:10
    tic
    p = t;
    p(randi(n,9000,1)) = 0;
    A1_10(:,:,:,j1) = A1_10(:,:,:,j1).*p;
    w{1}{2}{3} =A1_10(:,:,:,j1);
    y1 = idualtree3D(w, J, Fsf, sf); 
end

so y1 will contans 10 images processed in that loop,now i want to find or dispalay the image which has minimum error(i.e calculating Mse),if it is not possible to display please tell how to find the image having minimum error

Make y1 an array

y1(j1) = ......

and then keep track of min MSE like you do for anything that you want to keep track of min or max:

best_j1 = 1
minMSE = inf;
for j1 = 1 : 10
  MSE(j1) = .... % Do calculation.  Make array in case we want to inspect
  if MSE(j1) < minMSE
    best_j1 = j1;
    minMSE = MSE(j1);
  end
end

Or find it after the loop, instead of keeping track inside the loop:

[sortedMSE indexes] = sort(MSE, 'descend');
minMSE = sortedMSE(1);
best_j1 = indexes(1);
