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?

It seems that your data is x(i) and y(i), and the associated 2*a+3 and 4*b+9. Yeah, they are all constants, nothing much to plot other than a single point, because your x and y values do not depend on i.
In addition, you probably should not thnik in terms of symbolic variables. If you want to optimize something numerically, use regular numerics, or else the Optimization Toolbox problem-based approach.
