Class TempLat::MomentumMultiplicity

template <typename T, size_t NDim>

ClassList > TempLat > MomentumMultiplicity

Computes, for each Fourier-space site, the multiplicity of modes sharing the same rounded momentum magnitude bin. Returns 1/multiplicity on eval. Generalized to arbitrary NDim. More...

Detailed Description

Unit test: ctest -R test-momentummultiplicity

@vocab-summary How many modes share the \(\|k\|\) of the current Fourier site — the weight a correctly normalised spectrum needs.
