evo_two_m()

std::tuple< IterativeExit, SRDef > syten::MPS::TDVP::LBOWorker::evo_two_m	(	SDef const	prefactor,
		Index const	lsite,
		Index const	rsite,
		Tensor< 2 > &	s
	)

Evolves two MPS tensors.

The site tensors are left in left-/right-canonical form with the central tensor placed in the argument s, its first leg is going to the left.
