java.lang.Objectjsci.maths.wavelet.BasisFunctionLibrary
public class BasisFunctionLibrary
This class is meant to be used for Fast Wavelet Transform, Matching Pursuit and related signal processing algorithm. The basic idea is to automatically build and compress a library of "basis functions". Using Morse Coding this class delivers very fast code without sacrificing anything. The only fee is the one you pay to build the object, and it is a one time fee. Note : this class should be rewritten to use the java.util collections starting with jdk1.2. This class is not meant to be used directly but rather, you should build on it. It supports only 1D data.
