get_coefficient()

void syten::get_coefficient	(	MPS::State const &	psi,
		Index	first_site,
		Tensor< 2 >	partial_contraction,
		Vec< Pair< Index, Sector > > &	partial_bases
	)

Recursively called helper to compute coefficients of a state.

Parameters

psi	state of which we calculate the coefficients
first_site	site on which we currently work
partial_contraction	contraction of psi with selected basis states to the left
partial_bases	selected bases states on sites to the left of first_site

If called on the last-plus-one site, prints the coefficient and the selected basis states on all sites.
