Wavelet toolbox $toolbox/matlab/icons/matlabicon.gif

The Wavelet Toolbox extends the MATLAB Technical Computing Environment and provides a comprehensive collection of routines for examining local, multiscale, or nonstationary phenomena.

Wavelet methods offer additional insight and performance in any application where Fourier techniques have been used. The toolbox is useful in many signal and image processing applications, including speech and audio processing, communications, geophysics, finance and medicine.

The Wavelet Toolbox provides point-and-click graphical tools and command line functions for analysis, synthesis, de-noising and compression of signals and images.
