Detailed Description

template<int d, typename NT, typename KERNEL>
class DiFfRG::IntegratorAngleQMC< d, NT, KERNEL >

GPU integrator for the integration of a function with one angle with quasi-Monte-Carlo. Calculates.

\[ \int dp\, d\text{cos}\, \frac{1}{(2\pi)^d} f(p, \text{cos}, ...) + c \]

with \( p^2 \) bounded by \( \text{x_extent} * k^2 \).

Template Parameters

NT	The numerical type of the result.
KERNEL	The kernel to integrate.
