Member Function Documentation
void sc::DenIntegrator::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::RadialAngularIntegrator.
void sc::DenIntegrator::set_compute_potential_integrals (int)
Call with non zero if the potential integrals are to be computed.
They can be returned with the vmat() member.
const double* sc::DenIntegrator::alpha_vmat () const [inline]
Returns the alpha potential integrals.
Stored as the lower triangular, row-major format.
const double* sc::DenIntegrator::beta_vmat () const [inline]
Returns the beta potential integrals.
Stored as the lower triangular, row-major format.
virtual void sc::DenIntegrator::init (const Ref< Wavefunction > &) [virtual]
Called before integrate.
Does not need to be called again unless the geometry changes or done is called.
virtual void sc::DenIntegrator::integrate (const Ref< DenFunctional > &, const RefSymmSCMatrix & densa = 0, const RefSymmSCMatrix & densb = 0, double * nuclear_grad = 0) [pure virtual]
Performs the integration of the given functional using the given alpha and beta density matrices.
The nuclear derivative contribution is placed in nuclear_grad, if it is non-null.
Implemented in sc::RadialAngularIntegrator.
