apply

template<class R , class P = std::map<size_t, typename R::value_type>>

std::function<void(const std::vector<std::vector<value_type>>&, const CVecRef<P>&, const VecRef<R>&)> molpro::linalg::itsolv::PSpaceMetric< R, P >::apply

adds the action of the metric on vectors in the P space, like the function for the kernel given to add_p(); needed with MetricStorage::Stored, ignored with MetricStorage::OnTheFly, and kept by the solver

pp_matrix

template<class R , class P = std::map<size_t, typename R::value_type>>

array::Span<value_type> molpro::linalg::itsolv::PSpaceMetric< R, P >::pp_matrix

the metric matrix in the P space, in the layout of the kernel matrix given to add_p(), which copies it
