Final value(x) given by fminimax function is coming same as the initial value (x0) passed to it?

x = fminimax(fun,x0);

I have checked by changing the initial value (i.e. x0) , still initial(x0) and final(x) values are same. What may be the possible reasons for such behavior?

Hi,

please provide your code. Is your function continuous?

[priti sharma]

yes sir, function is continuous. Small change in the value of x should affect the objective function. Any resolution of this problem, if you know.

Without code to test against, the best we can give is vague answers.
