% The per iteration information displayed contains the iteration number
% (|Iter|), total number of function evaluations performed thus far
% (|FuncEvals|), the function value at the current iterate
% (|F(X)|), and the norm of the gradient at the current iterate
% scaled by the problem size (|||||G(X)||||||/N|). After the final
% iteration is performed, the total iteration and function evaluations,
