exponentiate_factor_mpo()

Operator syten::MPS::SwappableTEBD::exponentiate_factor_mpo	(	Index const	i,
		Index const	j,
		Operator	op,
		SDef	c,
		Lattice const &	lat,
		std::vector< Pair< Index, Index > > const &	fermions
	)

Calculates exp(x*c*h) assuming that h only acts nontrivially on sites i and j and 'x' is '-i' for complex-valued compilations and '-1' for real-valued computations.
