    Syntax

    disp(lscheme)

    Description

    disp(lscheme) displays the properties of the lifting scheme lscheme:

    • Wavelet name

    • Lifting steps

    • Lowpass filter coefficients

    • Normalization factors

    The function also displays the properties of each lifting:

    • Type of step

    • Laurent polynomial coefficients

    • Maximum order of the corresponding Laurent polynomial

    Note

    To display a lifting scheme created using liftwave, see displs.

    Open Live Script

    Create a lifting scheme associated with the db3 wavelet.

    lsc = liftingScheme('Wavelet','db3');

    Display the lifting scheme properties.

    disp(lsc)
     	 Wavelet               : 'db3' 
	 LiftingSteps          : [4 × 1] liftingStep 
	 NormalizationFactors  : [2.3155 0.4319] 
	 CustomLowpassFilter   : [  ]
