Detailed Description

template<int MaxL>
struct occ::mults::CartesianMultipole< MaxL >

Traceless Cartesian multipole moments Theta_{tuv}.

Storage layout follows RInts: hermite_index(t,u,v) with all ranks from 0 to MaxL stored contiguously. Total size = nhermsum(MaxL).

Template Parameters

MaxL	Maximum multipole rank
