Error using fminusub (line 16) Objective function is undefined at initial point. Fminunc cannot continue.

Hello,

I am trying to run a code and it always gave me the same error message:

"Error using fminusub (line 16) Objective function is undefined at initial point. Fminunc cannot continue".

I really need some help with my initial starting values or objective function.

Any suggestions are welcomed!

Thanks!
