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.

GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.
