How can I modify this code to use parfor s=1:r?

Hi, I have reported here a very simple piece of code but it basically faces the same issues of my actual estimation code. Could you help me in modifying it to use parfor s=1:r? Thanks a lot!

r=20;
n=2;
m=3;
D=unidrnd(20,8,2);
upp=zeros(size(D,1),r,n);

for j=1:n
    A=unidrnd(10,m,n);

       parfor s=1:r
          B=unidrnd(10,m,n);

          C=A+B;   

       for i=1:size(C,1)
           for w=1:size(D,1)
               if all(C(i,:)==D(w,:))
                   upp(w,s,j)=1;  

               end
           end
       end

       end
  end

You could try something like this

r=20;
n=2;
m=3;
D=unidrnd(20,8,2);
upp=zeros(size(D,1),r,n);
for j=1:n
    A=unidrnd(10,m,n);
    parfor s=1:r
        B=unidrnd(10,m,n);
        C=A+B;
        % Make a temporary vector to build up in the FOR loops below
        tmp = zeros(1, size(D,1));
        for i=1:size(C,1)
            for w=1:size(D,1)
                if all(C(i,:)==D(w,:))
                    % Assign an element of 'tmp'
                    tmp(w) = 1;
                end
            end
        end
        % Assign all of 'tmp' into 'upp'.
        upp(:, s, j) = tmp;
    end
end
