Function: fwtlength

FWTLENGTH  FWT length from signal
  Usage: L=fwtlength(Ls,w,J);

  FWTLENGTH(Ls,w,J) returns the length of a Wavelet system that is long
  enough to expand a signal of length Ls. Please see the help on
  FWT for an explanation of the parameters w and J.

  If the returned length is longer than the signal length, the signal
  will be zero-padded by FWT to length L.

  In addition, the function accepts flags defining boundary extension
  technique as in FWT. The returned length can be longer than the
  signal length only in case of 'per' (periodic extension).
