Display lifting scheme

Syntax

• S = displs(LS,FRM)
  

Description

S = displs(LS,FRM) returns a string describing the lifting scheme LS. The format string FRM (see sprintf) builds S.

displs(LS) is equivalent to DISPLS(LS,'%12.8f')

For more information about lifting schemes, see lsinfo.

Examples

• % Start from the Haar wavelet and get the
  % corresponding lifting scheme.
  lshaar = liftwave('haar');
  
  % Visualize the obtained lifting scheme.
  displs(lshaar);
  
  lshaar = {...                            
  'd'             [ -1.00000000]  [0]  
  'p'             [  0.50000000]  [0]  
  [  1.41421356]  [  0.70710678]  []   
  };                                   
  
  % Add a primal ELS to the lifting scheme.
  els = {'p',[-0.125 0.125],0};
  lsnew = addlift(lshaar,els);
  displs(lsnew);
  
  lsnew = {...                                        
  'd'             [ -1.00000000]              [0]  
  'p'             [  0.50000000]              [0]  
  'p'             [ -0.12500000  0.12500000]  [0]  
  [  1.41421356]  [  0.70710678]              []   
  };
