Functions
Vec< SDef >	syten::diagonal (Tensor< 2 > const &m, bool const order=true)
	Returns a vector of diagonal values, repeated according to the multiplicities of the tensor blocks. More...
SRDef	syten::invertDiagonal (Tensor< 2 > &m)
	Inverts a rank-two tensor in-place by inverting all reduced dense and CGC-space sparse blocks. More...
Tensor< 2 >	syten::sqrt (Tensor< 2 > inp)
	Returns the square root of the diagonal input matrix. More...
SDef	syten::trace (Tensor< 1 > const &a)
	Calculates the trace of a rank-1 tensor. More...
SDef	syten::trace (Tensor< 2 > const &a)
	Calculates the trace of a rank-2 tensor. More...
SRDef	syten::von_neumann_entropy (Tensor< 2 > const &s)
