orthonormalise()

template<typename Vec , typename It >

static void syten::Krylov::OrthoPolicies::TwoSiteVariational::orthonormalise ( Vec &  v, It  from, It  to, IterativeConfig const &  conf, IterativeExit &  e  )

inlinestatic

Orthonormalises v against the specified vectors using first orthogonalise_variational_two_site anmd then orthogonalise_variational.

This way, the larger variational subspace of two sites can be exploited while orthogonality is preserved exactly even after truncation.

Template Parameters

Vec	type of the vector to orthogonalise
It	type of the iterator behind which we can access the orthogonal vectors

Parameters

v	input and output vector to orthogonalise
from	first element of the set of vectors against which to orthogonalise, which have to be orthogonal.
to	one-past-the-end element of the set of vectors against which to orthogonalise.
conf	configuration to use
e	exit object, used to signal error conditions
