MATLAB: How to replace the optimset with equivalent optimoptions

differential equationsfsolvesolve

Hi all
using Fsolve, I am getting into difficulties and want to use Jacobian and Hessian as well , but first I need to pass from optimset to optimoptions
currently my Options are :
options = optimset('Display','iter','MaxFunEvals',1e6,'MaxIter',1e6,'TolFun',1e-3,'DerivativeCheck','on','Diagnostics','on');
so first, I need to have the equivalent optimoptions and then include Jacobian and Hessian.
since for some of my input data no solution is found ( Func-Count = 1.5e+7 ) , I need to imrpove my solution

Why not just,
options = optimoptions(@fsolve, 'Display','iter','MaxFunEvals',1e6,'MaxIter',1e6,...
'TolFun',1e-3,'DerivativeCheck','on','Diagnostics','on');
