Function: wfilt_qshifta
WFILT_QSHIFTA  Improved Orthogonality and Symmetry properties 

  Usage: [h,g,a] = wfilt_qshifta(N);

  [h,g,a]=wfilt_qshift(N) with N in {1,2,3,4,5,6,7} returns
  Kingsbury's Q-shift wavelet filters for tree A.

  Examples:
  ---------
  :
    figure(1);
    wfiltinfo('qshifta3');
