Hello all,

I am facing a logical problem like,

N =10;

syms a,b

for i = 1:N

y(i)=2*a+3;

x(i)=4*b+9;

fun(i) = mean((y(i)-x(i))^2);

end

data=sum(fun);

after optimization we get values of a,b and value of data properly ,but now I want to plot data. But here data is a single value. How i can proceed it?
