Harmonics

For harmonics.

harmonics_decomposition(basis_pg, pg, rank, head='Q')

Harmonics decomposition in terms of basis PG.

Parameters:

• basis_pg (str) – basis PG.

• pg (str) – PG expressed by basis PG.

• rank (int) – rank.

• head (str, optional) – type, Q/G ?

Returns:

decomposition info., [(harm_tag, [(coeff,basis)].

Return type:
