Double check that the "fminunc" function is correct. Small errors in the function to minimize could cause for very unexpected results.
Additionally, setting 'SpecifyObjectiveGradient' to true and defining a gradient function might drastically improve your solution.
Please see the following link for information on defining a gradient for the objective function:
