How to optimize exponential objective function with two variable in convex problem?

I am trying to optimize Pi* and Pj* by using convex optimization but due to exponential objective function and mu_n as non-negative constraint, i am getting errors. This algorithm is based on successive convex approximation. Iterative step size is 0.1, Please tell me where is my mistake?

If you get errors, be so kind to share the messages with the readers. It is easier to understand the problem, if the error message is known.

Thanks for your kind reply,

I am attaching the error doc. Should i use splitting conic solver (scs) with CVX tool for solving exponential objective function?

Screenshots are less useful than posting text as text. By the way, your Windows license is not activated.

I guess, that this is not the right way to call the tool. Remember that in

minimize(-(Mn-mu_n*(1+exp(-an*(gnx*(Pi+Pj)-bn)))))

the contents inside the parentheses is a number, isn't it? I guess you have to provide a function handle, but I'm not familiar with the CVX tool. The error message means, that "cvx_problem" is called as a function, but it is a script instead - this means without input arguments.

Thank you,

I'll take care of your advice for further, I think you are right and i am working on my mistaken.
