The results display problem

My code ishere. How about displaying every x and r from 1 to 4?

A= [1.02 0.95 0.77 0.67 0.56 0.30 0.16 0.01]; 
b = [0.39 0.32 0.22 0.18 0.15 0.12 0.13 0.15];
for i = 1:4
    num = 10.^(-i);
    A = A+num;
    b = b+num;
    [U,S,V] = svd(A,0);
    x = V.*(S.^(-1)).*U';
    r = rank(A);
end
disp(x);
disp(r);

A= [1.02 0.95 0.77 0.67 0.56 0.30 0.16 0.01]; 
b = [0.39 0.32 0.22 0.18 0.15 0.12 0.13 0.15];
for i = 1:4
    num = 10.^(-i);
    A = A+num;
    b = b+num;
    [U,S,V] = svd(A,0);
    x(:,:,i) = V.*(S.^(-1)).*U';
    r(i)= rank(A);
end
disp(x);
