# MATLAB: How to modify this code to use parfor s=1:r

forfor looploopsparallel computingParallel Computing Toolboxparfor

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

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;    endend
