It is used, for example, by QNewtonOpt objects. Based on the value of inverse_hessian_ x and g may be reversed (see Schlegel, Ab initio Methods in Quantum Chemistry I, 1987, p 10). Member Function Documentation void sc::HessianUpdate::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::SavableState. Reimplemented in sc::DFPUpdate. The documentation for this class was generated from the following file: update.h
