Why the same starting value gives different result when optimization?

    I am doing maximum likelihood estimation. I try 2 starting values x1
    and x2 during the optimization.
    I start Matlab, run the program 3 times, with the starting values x1,
    then x2, and back to x1. Now the problem is, the outcome from the
    first run and the third run is different!
    I am confused.
    Are the optimization options parameters changed during the
    optimization?

    What function are you using? Would you like to share your code?
