Other Real Wavelets

Some other real wavelets are available in the toolbox.

Reverse Biorthogonal Wavelet Pairs: rbioNr.Nd

This family is obtained from the biorthogonal wavelet pairs previously described.

You can obtain a survey of the main properties of this family by typing waveinfo('rbio') from the MATLAB command line.

Gaussian Derivatives Family: gaus

This family is built starting from the Gaussian function:

by taking the derivative of 
f.

The integer is the parameter of this family and in the previous formula,

is such that:

where is the derivative of  f.

You can obtain a survey of the main properties of this family by typing waveinfo('gaus') from the MATLAB command line.

FIR Based Approximation of the Meyer Wavelet: dmey

See [Abr97] page 268.

This wavelet is a FIR based approximation of the Meyer wavelet, allowing fast wavelet coefficients calculation using DWT.

You can obtain a survey of the main properties of this wavelet by typing waveinfo('dmey') from the MATLAB command line.
