when used (while loop) as stopping condition of process ,we specified the value of error may be 0.001 or 0.00001
if I have number of iteration ,How can plot the error with iteration numbers?

[i j]=ndgrid(1:111,1:33);
MPD=1;
while(MPD>0.00001);
G=(sum(sum((abs(v_now-v_prev)))));
MPD=G/(m*n);
% your code
end

You are not doing anything inside the loop. Try
iter=0;
MPD=1;
while(MPD>0.00001); %Run this until convergence
G=(sum(sum((abs(v_now-v_prev)))));
MPD=G/(m*n); %error stoping criteria
iter=iter+1; % Iteration counter increment
hold on
plot(iter,MPD)
end
