           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.
