Wavelets
The Discrete Transforms package, which is included with Maple, now contains numerical wavelet transforms. It provides the ability to obtain the coefficients for many well-known classes of wavelets for varying filter lengths, including Daubechies and Bi-Orthogonal Spline wavelets, and to apply these wavelet transforms to discrete data.

Features include:

• Ability to compute forward and inverse numerical wavelet transforms by using a variety of end-conditions
• Wavelet Plot tool for visualizing wavelets
• Wavelet filters for the common families of wavelets, including  Daubechies Wavelets, Symlets, Coiflets, Battle-Lemarie (orthogonal spline) Wavelets, and Biorthognal Spline Wavelets
• Ability to define your own wavelet filter
