multi_grow()

std::tuple< bool, SRDef, Index > syten::IPEPSv2::CornerTransferMatrix::multi_grow	(	State const &	psi,
		Truncation const &	trunc,
		Index const	max_steps,
		SRDef const	sv1_conv
	)

Grows the CTM at most max_steps times or until the first singular values changed by less than sv1_conv.

Returns

a tuple of is-converged,change-in-last-step,number-of-steps
