mackey::find_permutation
std::vector< pScalar > find_permutation(const std::vector< T > &A, const std::vector< T > &B)
If vector B is permutation of vector A i.e. B= A * sigma then returns permutation sigma.

mackey::ChangeBasis
Change of basis matrices needed for the equivariant tensor product.
Definition: ChangeBasis.hpp:24

mackey::ChangeBasis::canon_to_left
std::vector< pScalar > canon_to_left
The permutation from the canonical basis to the left convenient basis.
Definition: ChangeBasis.hpp:28

mackey::ChangeBasis::ChangeBasis
ChangeBasis(const rank_t &A, const rank_t &B, bool set_conv_to_canon, bool set_canon_to_conv)
