- function LSR = lsdual(LS)
- %LSDUAL Dual lifting scheme.
- % LSD = LSDUAL(LS) returns the lifting scheme LSD
- % associated to LS. LS and LSD are issued of the
- % same polyphase matrix factorisation PMF, where
- % PMF = LS2PMF(LS). So [LS,LSD] = PMF2LS(PMF,'t').

- % N.B.: LS = LSDUAL(LSDUAL(LS)).
