Member Function Documentation

void DFPUpdate::save_data_state ( StateOut & s ) [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 HessianUpdate. Reimplemented in BFGSUpdate.
