Constructor & Destructor Documentation

sc::CLKS::CLKS (const Ref< KeyVal > &)

This KeyVal constructor reads the following keywords:. .IP "integrator" 1c Specifies the DenIntegrator that will be used to integrate the density functional. The default is RadialAngularIntegrator.

functional

Specifies the DenFunctional that will be used to compute the exchange/correlation contribution. This is no default.

Member Function Documentation

RefSymmSCMatrix sc::CLKS::effective_fock () [protected, virtual]

Returns closed-shell Fock matrix in MO basis (including XC contribution for KS DFT).

Reimplemented from sc::CLSCF.

void sc::CLKS::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::CLSCF.

int sc::CLKS::value_implemented () const [virtual]

Information about the availability of values, gradients, and hessians.

Reimplemented from sc::Function.
