           Save the base classes (with save_data_state) and the members in the
           same order that the StateIn CTOR initializes them.

Constructor & Destructor Documentation
   sc::DFPUpdate::DFPUpdate (const Ref< KeyVal > &)
       The KeyVal constructor reads the following keywords:

       xprev
           The previous coordinates can be given (but is not recommended). The
           default is none.

       gprev
           The previous gradient can be given (but is not recommended). The
           default is none.

Member Function Documentation
   void sc::DFPUpdate::save_data_state (StateOut &) [virtual]
       Save the base classes (with save_data_state) and the members in the
       same order that the StateIn CTOR initializes them. This must be
       implemented by the derived class if the class has data.

       Reimplemented from sc::HessianUpdate.

       Reimplemented in sc::BFGSUpdate.
