disp

Display lifting scheme

Since R2021a

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.

Examples

Display Lifting Scheme Properties

Create a lifting scheme associated with the db3 wavelet.

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

Display the lifting scheme properties.

	 LiftingSteps          : [4 × 1] liftingStep 
	 NormalizationFactors  : [2.3155 0.4319] 
	 CustomLowpassFilter   : [  ]
