fminicon optimization and NaN problem ,
I have a function that i am trying to minimize it using the fminicon optimization function and the results return are always NaN, i have debugged the program and checked the reason of the NaN it was because i have some results in the function equal to zero then in the function this results should take log and it will give -inf the when multiplied by zero it will give NaN,
my question is that can i do anything to make the fminicon function overcome the problem of the NaN?
i would really appreciate your help
thanks in advance

If you give a starting point that is feasible (no NaN values), and use the interior-point algorithm, then fmincon should be able to handle the issue.
You could also write your objective function to explicitly look for the issue and return proper values.
