class HarmonicSelectionRules

Rule-based harmonic selection for different quadrature types.

Implements the specific mathematical rules for selecting spherical harmonics based on quadrature type, dimension, and operator construction method.

Public Static Functions

static std::vector<AngularQuadrature::HarmonicIndices> SelectHarmonics(const SelectionParameters &params)

Select harmonics using predetermined mathematical rules.

Parameters:

params – Selection parameters including quadrature type and dimensions.

Returns:

Vector of selected harmonic indices.

struct SelectionParameters

Input parameters controlling harmonic selection.
