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
