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?

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.
