generateSampledState()

State syten::MPS::RandomState::generateSampledState	(	Lattice const &	lat,
		std::string const &	secDesc,
		Index const	maxStates,
		Index const	maxBlocksize,
		Index const	sampled_initOperators,
		bool const	bpo_quiet,
		std::ostream &	err
	)

Generates a full sampled state using generateSampledProductState() internally and offers logging facilities.

Parameters

lat	underlying lattice
secDesc	string describing the target sector, parsed wrt lat
maxStates	generate this many states and truncate down to this bond dimension
maxBlocksize	truncate down to this maximal blocksize
sampled_initOperators	apply this many operators unconditionally in generateSampledProductState()
bpo_quiet	if true, do not output progress dots
err	place messages in this stream
