Function: dwiltlength

DWILTLENGTH  DWILT/WMDCT length from signal
  Usage: L=dwiltlength(Ls,M);

  DWILTLENGTH(Ls,M) returns the length of a Wilson / WMDCT system with
  M channels system is long enough to expand a signal of length
  Ls. Please see the help on DWILT or WMDCT for an explanation of the
  parameter M.

  If the returned length is longer than the signal length, the signal will
  be zero-padded by DWILT or WMDCT.

  A valid transform length must be divisable by 2M. This
  means that the minumal admissable transform length is :

    Lsmallest = 2*M;

  and all valid transform lengths are multipla of Lsmallest*
