Hello,
I am trying to use the fmincon with a external function definition.
I ran the example at https://www.mathworks.com/help/optim/ug/fmincon.html and it wroked as described
I tried to define the function as an external function as shown below.
% script calling fmincon start
clc
clear all
x0=[-1,2];
A=[1,2];
b=1;
zeta=fmincon(fun,x0,A,b);
% script calling fmincon end
% script defining fun start
function q=fun(x)
q=100*(x(2)-x(1)^2)^2+(1-x(1))^2;
end
% script defining fun end
I get this error: Not renough input arguments from the fun script
Not sure how to fix this probem
Thank you

Works for me after changing "fun" in "@fun":
% script calling fmincon start
clc
clear all
x0=[-1,2];
A=[1,2];
b=1;
zeta=fmincon(@fun,x0,A,b)
% script calling fmincon end
% script defining fun start
function q=fun(x)
q=100*(x(2)-x(1)^2)^2+(1-x(1))^2;
end
% script defining fun end
