matlab: fmincon, pass variables into nonlcon

Question

I know its a stupid question, but I have no idea how to solve it... Lets say I have something like:

x = fmincon(@myfun,x0,A,b,Aeq,beq,lb,ub,@mycon)

and later on :

function [c,ceq] = mycon(x)
c = ...     
ceq = ...   

How to pass additional variables into @mycon , such as

function [c,ceq] = mycon(x, variable)
if variable == 1 
    c = ...     
    ceq = ... 
else   
    c = ...     
    ceq = ... 
end

Thanks :)

Answer 1

You pass mycon as anonymous function:

   x = fmincon(@myfun,x0,A,b,Aeq,beq,lb,ub,@(xx)mycon(xx,variable))

Note that variable is fixed at the moment the fmincon line is called.
