leftnorm() [2/2]

SRDef syten::MPS::LBOState::leftnorm	(	Truncation const &	trunc = Truncation(),
		DropNorm const	dropN = DropNorm::Yes
	)

Left-normalises the entire state from left to right.

Parameters

trunc	truncation parameters to apply. If trunc.notTruncating() is true, does a QR, otherwise a SVD decomposition.
dropN	if DropNorm::Yes, normalises the transfer tensors to have norm one.

Returns

an upper bound on the error incurred during the truncations, the actual error is likely lower.
