sp_wrapup() [1/2]

template<typename VectorType , typename StreamType >

void syten::Krylov::SolverPolicies::ExponentialFineOverlap::sp_wrapup ( DenseTensor< 2, SDef > const &  projected_mat, std::vector< VectorType > const &  krylov, SRDef  initialnorm, SDef  toffset, SDef  tbeg, SDef  dt, Index  num_points, std::vector< VectorType > const &  overlapee, std::vector< StreamType > &  output  )

inline

Wrap-Up implementation discretizing the timestep dt into num_points smaller timesteps in which overlaps with the vectors stored in 'overlapees' will be computed and streamed into the outstreams stored in the vector 'output'.

This is the overload for multiple 'overlapee' vectors.

Parameters

projected_mat	projected Hamiltonian matrix
krylov	vector of Krylov vectors
initialnorm	initial norm of the input Krylov vector
toffset	time between the initialisation of the Krylov subspace and the current starting point
tbeg	current starting point
dt	time step to slice, starting at tbeg. Evolution occurs from tbeg-toffset, i.e. we add toffset to dt always
num_points	number of points to evaluate, starting at tbeg+dt/num_points and going to tbeg+dt
overlapee	vector of vectors with which to evaluate overlaps
output	vector of streams into which we write the results
