Detailed Description

template<typename NT, typename KERNEL>
class DiFfRG::Integrator4DTBB< NT, KERNEL >

Integrator for the integration of a 4D function with three angles with TBB. Calculates.

\[ \int dp\, d\text{cos}_1\, d\text{cos}_2\, d\phi\, \frac{1}{(2\pi)^4} \sqrt{1-\text{cos}_1^2} f(p, \text{cos}_1, \text{cos}_2, \phi, ...) + c \]

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

Template Parameters
NTThe numerical type of the result.
KERNELThe kernel to integrate.
