I am trying to do Global search with fmincon as follows after following the tutorial https://www.mathworks.com/help/gads/example-finding-global-or-multiple-local-minima.html:

problem = createOptimProblem('fmincon',...
    'objective',f,...
    'x0',x0,...
    'A',A,...
    'b',b,...
    'Aeq',Aeq,...
    'beq',beq,...
    'lb',lb,...
    'ub',ub,...
    'options',...
    optimoptions(@fmincon,'Algorithm','sqp','Display','off'));
gs = GlobalSearch('Display','iter');
[x,fval] = run(gs,problem)

However, I am getting the following error:

Error using createOptimProblem (line 107)
No field A exists for PROBLEM structure.
Type "help createOptimProblem" for a list of valid fields for each solver.
Error in QPSK_optim_global (line 84)
    problem = createOptimProblem('fmincon',...
