Detailed Description

template<int dim, typename NT, typename KERNEL, typename ExecutionSpace>
requires (dim > 0)
class DiFfRG::QuadratureIntegrator< dim, NT, KERNEL, ExecutionSpace >

This class performs numerical integration over a d-dimensional hypercube using quadrature rules.

Template Parameters

dim	The dimension of the hypercube, which can be between 1 and 5.
NT	numerical type of the result
KERNEL	kernel to be integrated, which must provide the static methods kernel and constant
ExecutionSpace	can be any execution space, e.g. GPU_exec, TBB_exec.
