inline Hermiticity sequant::mbpt::default_hermiticity(OpClass cls)

Returns:

the default Hermiticity for an operator of the given OpClass: general operators are matrix elements of (anti-)Hermitian operators and default to Hermitian; (de)excitation operators (cluster amplitudes, etc.) are not Hermitian. This default can be overridden per operator in the OpRegistry (e.g. to keep reference equations that assumed the legacy conjugate-symmetric amplitudes).
