3.9.2. horton.part.becke – Becke partitioning

class horton.part.becke.BeckeWPart(coordinates, numbers, pseudo_numbers, grid, moldens, spindens=None, local=True, lmax=3, k=3)

Bases: horton.part.base.WPart

Optional arguments: (that are not defined in WPart)

k

The order of the polynomials used in the Becke partitioning.

clear()

Discard all cached results, e.g. because wfn changed

compute_pseudo_population(index)

do_all()

Computes all properties and return a list of their keys.

do_charges(instance)

do_density_decomposition(instance)

do_hartree_decomposition(instance)

do_moments(instance)

do_partitioning(instance)

do_populations(instance)

do_spin_charges(instance)

get_grid(index=None)

Return an integration grid

Optional arguments:

index

The index of the atom. If not given, a grid for the entire system is returned. If self.local is False, a full system grid is always returned.
