Abstract

Based on the SplineWavelet package, we have developed an updated ver- sion of the general wavelet analysis package called Wavelet. The new version incorporates many new capabilities that become available due both to the recent development of wavelet theory, and the new features of Mathematica Version 3. We discuss changes in the function definitions and their implica- tions, and present the details of some of the most important new features. The new Compile function can speed up the computation by a factor of six to seven. Palettes can serve as an easy-to-use GUI for wavelet analysis. 1 Introduction Wavelet [1][2] is a subject of recent extensive study in a variety of fields including mathematics, signal processing, statistics, and engineering. Due to its ability of providing time-frequency representa
