WaveLab is a collection of Matlab functions that have been used by the authors and collaborators to implement a variety of algorithms related to wavelet analysis. A partial list of the techniques made available: * orthogonal and biorthogonal wavelet transforms, * translation-invariant wavelets, * interpolating wavelet transforms, * cosine packets, * wavelet packets, * matching pursuit, and a lot more; Here is a more detailed introduction.
PyWavelets is a Python module for calculating Simple and Inverse Discrete Wavelet Transform, as well as Wavelet Packets and Stationary Wavelet Transform.
