DFPUpdate (const Ref< KeyVal > &)
The KeyVal constructor reads the following keywords: void save_data_state (StateOut &)
Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. void update (const RefSymmSCMatrix &ihessian, const Ref< Function > &, const RefSCVector &xnew, const RefSCVector &gnew)

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.

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.
