  Undocumented


`h_apply_ddci_pt2 <http://github.com/LCPQ/quantum_package/tree/master/src/DDCI_selected/H_apply.irp.f_shell_15#L1271>`_
  Calls H_apply on the HF determinant and selects all connected single and double
  excitations (of the same symmetry). Auto-generated by the ``generate_h_apply`` script.


`h_apply_ddci_pt2_diexc <http://github.com/LCPQ/quantum_package/tree/master/src/DDCI_selected/H_apply.irp.f_shell_15#L776>`_
  Generate all double excitations of key_in using the bit masks of holes and
  particles.
  Assume N_int is already provided.


`h_apply_ddci_pt2_monoexc <http://github.com/LCPQ/quantum_package/tree/master/src/DDCI_selected/H_apply.irp.f_shell_15#L1086>`_
  Generate all single excitations of key_in using the bit masks of holes and
  particles.
  Assume N_int is already provided.


`h_apply_ddci_selection <http://github.com/LCPQ/quantum_package/tree/master/src/DDCI_selected/H_apply.irp.f_shell_15#L530>`_
  Calls H_apply on the HF determinant and selects all connected single and double
  excitations (of the same symmetry). Auto-generated by the ``generate_h_apply`` script.


`h_apply_ddci_selection_diexc <http://github.com/LCPQ/quantum_package/tree/master/src/DDCI_selected/H_apply.irp.f_shell_15#L1>`_
  Generate all double excitations of key_in using the bit masks of holes and
  particles.
  Assume N_int is already provided.


`h_apply_ddci_selection_monoexc <http://github.com/LCPQ/quantum_package/tree/master/src/DDCI_selected/H_apply.irp.f_shell_15#L331>`_
  Generate all single excitations of key_in using the bit masks of holes and
  particles.
  Assume N_int is already provided.
