waveinfo provides information on all wavelets within the toolbox.
waveinfo('wname') provides information on the wavelet family whose short name is specified by the string 'wname'. Available family short names are listed in the table below.
Wavelet Family Short Name
Wavelet Family Name
Reverse biorthogonal wavelets
Discrete approximation of Meyer wavelet
Mexican hat wavelet
Complex Gaussian wavelets
Frequency B-Spline wavelets
Complex Morlet wavelets
The family short names can also be user-defined ones (see wavemngr for more information).
waveinfo('wsys') provides information on wavelet packets.
waveinfo('db') DBINFO Information on Daubechies wavelets. Daubechies Wavelets General characteristics: Compactly supported wavelets with extremal phase and highest number of vanishing moments for a given support width. Associated scaling filters are minimum-phase filters. Family Daubechies Short name db Order N N strictly positive integer Examples db1 or haar, db4, db15 Orthogonal yes Biorthogonal yes Compact support yes DWT possible CWT possible Support width 2N-1 Filters length 2N Regularity about 0.2 N for large N Symmetry far from Number of vanishing moments for psi N Reference: I.
