I did the same way as in the optimization toolbox guide.
MATLAB: I am getting an error message ‘not enough input arguments’ on running Rosenbrock’s function using the optimization tool box solver ‘fmincon’ solver. How to correct it

You have miscalculated your A and b. You can use vert2lcon to obtain them automatically,
When I do so, I obtain
>> [A,b]=vert2lcon([P1;P2;P3;P4])A = -0.8944 -0.4472 0 -1.0000 0 1.0000 0.8944 -0.4472b = -2.2361 -1.0000 3.0000 3.1305Substituting these into your code results in,
Hi Ektor,
You have done a good work except for two small flaws, but crucial ones. Here are the corrected scripts:
function [c,ceq] = unitdisk3(x)c = [ x(1)-0.999, -x(2)-0.999 , - x(3) +0.001 ];ceq = [];endg=randn(1000,1);u=randn(1000,1);options = optimoptions('fmincon','Display','off', 'Algorithm', 'active-set');ff = @(x) sum((g(2:end)- x(1)- x(2)*(g(1:end-1)-x(1)) - u(2:end)*x(3)).^2);xx = fmincon(ff,[0.1 0.2 0.3],[],[],[],[],[],[],@unitdisk3,options);Good luck.
