Error in fmincon while I have the optimization toolbox

I just registered a trial version and activated it today. When I use the "ver" command, I can see the "optimization toolbox" installed. However, I am unable to run the following code:

% Define the objective function 
fun = @(x) (x(1) - 1)^2 + (x(2) - 2.5)^2;
% Set the initial point and bounds 
x0 = [0,0]; lb = [-1,-1]; ub = [3,3];
% Run the optimizer 
options = optimoptions('fmincon','Display','iter'); 
[x,fval] = fmincon(fun,x0,[],[],[],[],lb,ub,[],options);

Local minimum found that satisfies the constraints.

Optimization completed because the objective function is non-decreasing in 
feasible directions, to within the value of the optimality tolerance,
and constraints are satisfied to within the value of the constraint tolerance.

The error message I receive is:

"Function or variable 'eml_option' is not recognized.

Error in optim.coder.validate.checkProducts

Error in fmincon

Error in bayes_al (line 11) [x,fval] = fmincon(fun,x0,[],[],[],[],lb,ub,[],options);"

Could you please help me with this issue?

[Torsten]

Do you somehow work with embedded MATLAB functions because of the "eml_option" in the error message ?

Or do you use a function or variable with this name ?

[ikarry]

No, all codes are displayed above

Very crazy, these codes were from ChatGPT, and I am trying my best to solve this problem, but failed and I am crazy

[Torsten]

You didn't anwer my question: Do you somewhere use a Function or variable 'eml_option' ?

As you can see above, your code works in R2022b, and I guess this is the same as your test version.

What if you use

% Define the objective function 
fun = @(x) (x(1) - 1)^2 + (x(2) - 2.5)^2;
% Set the initial point and bounds 
x0 = [0,0]; lb = [-1,-1]; ub = [3,3];
[x,fval] = fmincon(fun,x0,[],[],[],[],lb,ub);
