DiFfRG::internal::MatsubaraStorage Class Reference

A class that stores Matsubara quadrature points and weights for a given T, E. Its main purpose is to avoid recomputing the quadrature points and weights for each Matsubara integrator and provide a search algorithm to find previously computed Matsubara quadratures. More...
