Functions
DenseTensor< 2, SRDef >	syten::mutualInfo::allSiteEntropy (MPS::State &input, Index const width)
	Calculates the two site entropy of a state on all sites i != j and single site entropy on all sites i == j Works identical to entropyTwoSite but reduces the overhead by storing and reusing some Tensors. More...
SRDef	syten::mutualInfo::entropy (Tensor< 2 > densityMatrix)
	Calculates the entropy of a density matrix. More...
SRDef	syten::mutualInfo::entropyOneSite (MPS::State &input, Index const site)
	Calculates the single site entropy of a state. More...
SRDef	syten::mutualInfo::entropyTwoSite (MPS::State &input, Index site1, Index site2)
	Calculates the two site entropy of a state. More...
std::tuple< SRDef, std::vector< Index > >	syten::mutualInfo::optimal_order (DenseTensor< 2, SRDef > mInfo)
	Calculates the optimal order of the network given the mutual Information. More...

Detailed Description
