Function: wfilt_dden

WFILT_DDEN  Double-DENsity DWT filters (tight frame)
  Usage: [h,g,a] = wfilt_dden(N);

  [h,g,a]=WFILT_DDEN(N) computes oversampled dyadic double-density DWT
  filters. 
  The redundancy of the basic filterbank is equal to 1.5.

  Examples:
  ---------
  :

    wfiltinfo('dden5');
