Function: wfilt_hden

WFILT_HDEN  Higher DENsity dwt filters (tight frame, frame)
  Usage: [h,g,a] = wfilt_hden(K);

  [h,g,a]=WFILT_HDEN(K) with K in {1,2,3,4} returns Higher DENsity 
  dwt filters (tight frame, frame) from the reference. The filterbanks 
  have 3 channels and unusual non-uniform subsamplig factors [2,2,1].

  Examples:
  ---------
  :
    wfiltinfo('hden3');

  :
    wfiltinfo('ana:hden4');
