In this link, ro only a 2d vector, si you can simply write by hand the function. Here, I want to generalize it for different values of n. Can you fill the " Thank you for your code. So, if you say that what is equivalence class set is a n-dimension vector, matlab know that x in the fun functionwill be a n-dimension vector?

I still have an error, but I guess the hardest part is done :. Numerical solvers don't work with symbolic variables. Just fill the ' I get this error with this code: fminunc stopped because the size of the current step is less than what is disease and its causes default value of the step size tolerance.
