Dear Ipopt mailing list members,
I would like to use Ipopt to find the minimum of a function with some constraints. The problem is that there is no easy analytical expression for the gradient of the function, nor for the Hessian, but there is a simple analytical expression for the jacobian of the constraints. 

Can Ipopt handle this? How should I do?
