dyn_sltcnd_excit

public function dyn_sltcnd_excit(ref, exc, tParity, assert_occupation) result(hel)

@brief Evaluate Matrix Element for different excitations using the Slater-Condon rules.

@details This generic function uses run time dispatch. This means that exc can be any subtype of class(Excitation_t). For performance reason it is advised to use sltcnd_excit, if the actual type is known at compile time.

@param[in] ref, The reference determinant as array of occupied orbital indices. @param[in] exc, An excitation of type excitation_t. @param[in] tParity, The parity of the excitation.

Arguments

Type	Intent	Optional		Name
integer,	intent(in)		::	ref(nel)
class(Excitation_t),	intent(in)		::	exc
logical,	intent(in)		::	tParity
logical,	intent(in),	optional	::	assert_occupation
