sp_result()

template<typename Vec >

auto syten::Krylov::SolverPolicies::Exponential::sp_result ( std::vector< Vec > const &  krylov, SRDef  initialnorm, SDef  _idt  ) const

inline

Calculates \( \mathrm{exp}(t H) |\psi\rangle \) where \( |\psi \rangle \) is taken as the first element of krylov multiplied by its initial norm initialnorm and t = _idt.

Requires a previous call to convergence() to calculate the coefficients needed.
