I use fminunc to find local optimum of a function and get a warning: "fminunc stopped because it exceeded the function evaluation limit, options.MaxFunEvals = 3600 (the default value)."
I know how to set options.MaxFunEvals, but I don't know what's the meaning of this parameter? The description in the document is "Maximum number of function evaluations allowed".
From my understanding, the termination parameter includes max number of iteration, change of step size, change of function value, change of gradient and so on. But I have no idea what "Maximum number of function evaluations allowed" means.
