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.
