int | print_molecule_when_changed_ |
It computes the energy of the molecule as a function of the geometry. The coordinate system used can be either internal or cartesian.
|
The KeyVal constructor.
|
|
An optimizer can call change coordinates periodically to give the function an opportunity to change its coordinate system. A return value of 0 means the coordinates were not changed. Otherwise, a transform object to the new coordinate system is return. The function object applies the transform to any objects it contains. This will obsolete the function data. Reimplemented from sc::Function.
|
|
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::Function.
Reimplemented in sc::MBPT2, sc::MBPT2_R12, sc::PsiWavefunction, sc::PsiSCF, sc::PsiCCSD, sc::PsiCCSD_T, sc::CLHF, sc::CLSCF, sc::HSOSHF, sc::HSOSSCF, sc::SCF, sc::UnrestrictedSCF, sc::OneBodyWavefunction, and sc::Wavefunction.
|
|
These are passed gradients and hessian in cartesian coordinates. The gradient and hessian in internal coordinates are computed. Reimplemented from sc::Function.
