Hi there I have a problem with fmincon function.
I have written the code belowe, when I have run it, Matlab run only one cycle and giving me the message
"Error using barrier
Objective function is undefined at initial point. Fmincon cannot continue.
Error in fmincon (line 824)
[X,FVAL,EXITFLAG,OUTPUT,LAMBDA,GRAD,HESSIAN] = barrier(funfcn,X,A,B,Aeq,Beq,l,u,confcn,options.HessFcn, ...
