  1. + New: There is now a new AutoDerivativeFunction class that + automatically computes the gradient of a function by employing + numerical difference quotients. This only, if the user function + does not provide the gradient function himself. This class can + replace the Function class as base + class for user defined Function + classes. +
    + This new class can be used if the user only implements the + value function but wants to call + also the gradient functions. +

  2. New: The Quadrature class now has a - conctructor that only accepts quadrature points and sets the + constructor that only accepts quadrature points and sets the weights to invalid values.
