Deriv

class psi4.core.Deriv

Bases: pybind11_builtins.pybind11_object

Computes gradients of wavefunctions

Methods Summary

compute(self, deriv_calc_type)	Compute the gradient
compute_df(self, arg0, arg1)	Compute the density-fitted gradient
set_deriv_density_backtransformed(self[, val])	Is the deriv_density already backtransformed? Default is False
set_ignore_reference(self[, val])	Ignore reference contributions to the gradient? Default is False
set_tpdm_presorted(self[, val])	Is the TPDM already presorted? Default is False
