LaplaceDenominator

class psi4.core.LaplaceDenominator

Bases: pybind11_object

Computer class for a Laplace factorization of the four-index energy denominator in MP2 and coupled-cluster

Methods Summary

denominator_occ(self)	Returns the occupied orbital Laplace weights of the factorized doubles denominator (nweights * nocc)
denominator_vir(self)	Returns the virtual orbital Laplace weights of the factorized doubles denominator (nweights * nvirt)

Methods Documentation

denominator_occ(self: psi4.core.LaplaceDenominator) → psi4.core.Matrix

Returns the occupied orbital Laplace weights of the factorized doubles denominator (nweights * nocc)

denominator_vir(self: psi4.core.LaplaceDenominator) → psi4.core.Matrix

Returns the virtual orbital Laplace weights of the factorized doubles denominator (nweights * nvirt)
