public abstract class Wavelet
extends java.lang.Object

Base class for describing wavelets. This code is inspired by that of JWave. The Wavelet_XXX classes which extend this base class are generated by the shell script below. The coefficients are scraped from http://wavelets.pybytes.com/. The script is called using: cat wavelets |while read f h; do curl "http://wavelets.pybytes.com/wavelet/$f/"|sh extract $f 2>/dev/null; done Where wavelets contains the name of each wavelet to generate (part of the URI Path, see above).
