I'm working with some multi-objective optimization and I've found some toolkits for that. To decide on which one to use I'm testing them with different trivial problems like the optimization of a can. But I´ve found that a commonly used problem to test them is this one
n=numel(x);
z=[1-exp(-sum((x-1/sqrt(n)).^2))
1-exp(-sum((x+1/sqrt(n)).^2))];
and it will be really useful for me to see a graphical representation of that function, but I'm struggling to plot it. Any advice is appreciated

Apparently ‘x’ is a vector. That means that ‘z’ produces only two values.
You could plot it as:
figure
plot(z, 'p')
however I doubt if that is going to be very meaningful.

That is all there is.
The result returned in ‘z’ for that ‘x’ is:
z =
1.0000
1.0000
It is only a point.
