class Hamiltonian_Eigen : public Hamiltonian<HilbertField>

Public Functions

Hamiltonian_Eigen(shared_ptr<model> the_model, const map<string, double> &value, sector _sec)

constructor

virtual void mult_add(vector<HilbertField> &x, vector<HilbertField> &y)

Applies the Hamiltonian: y = y +H.x.

Parameters:

• y – vector to which H.x is added to

• x – input vector

virtual void diag(vector<double> &d)

provides the diagonal d of H Used by the Davidson method

Parameters:

d – the diagonal of H (pre-allocated)
