Detailed Description

template<typename NT, typename KERNEL>
class DiFfRG::Integrator2Dpq0TBB< NT, KERNEL >

Integrator for 2+1D integrals over p, q0 and an angle using TBB. Calculates.

\[ \int dp dcos dq0 f(p, cos, q0) + c \]

Template Parameters

NT	Numerical type.
KERNEL	Kernel to integrate. Must have a static constant member function constant which supplies c and a static member function kernel which supplies the integrand.
