template<typename Iterator >

void syten::MPS::orthogonalise_variational_two_site ( State &  psi, Iterator  first, Iterator  last, Truncation const &  trunc  )

inline

variationally orthogonalise a state two sites at a time wrt a set of other states in-place

Parameters

psi	the state to be orthogonalised (in place)
first	the iterator to the first state of the set
last	the iterator to the "past the end" element
trunc	truncation specification
