Detailed Description

template<size_t Nq>
struct Xped::qarray< Nq >

Array of quantum numbers corresponding to Abelian or non Abelian symmetries. Just a thin wrapper over std::array<int,Nq> with some bracket operators, boolean functions, coefficient-wise arithmetics and output to with a streaming operator. \describe_Nq

Note

special typedefs not caught by Doxygen:
qarray2<Nq> = std::array<qarray<Nq>,2> : pair of quantum numbers in a two-legged tensor Biped
qarray3<Nq> = std::array<qarray<Nq>,3> : triplet of quantum numbers in a three-legged tensor Tripod (see Multipede)
qarray4<Nq> = std::array<qarray<Nq>,4> : quadruplet of quantum numbers in a four-legged tensor Quadruped (see Multipede)
