DiFfRG::QuadratureProvider Class Reference

A class that provides quadrature points and weights, in host and device memory. The quadrature points and weights are computed either the GSL quadratures or the MatsubaraQuadrature class. This avoids recomputing the quadrature points and weights for each integrator. More...

Detailed Description

A class that provides quadrature points and weights, in host and device memory. The quadrature points and weights are computed either the GSL quadratures or the MatsubaraQuadrature class. This avoids recomputing the quadrature points and weights for each integrator.
