SDef syten::MPS::overlap	(	State const &	b,
		State const &	a
	)

Returns the overlap \(\langle b | a \rangle\) between two states.

Parameters

b	the first state, to be complex-conjugated.
a	the second state, not complex-conjugate.

Returns

the overlap between the two states, i.e. \(\langle b | a \rangle\).
