DoubleWavelet Class

This class represents a double precision wavelet. There are fives types of built in wavelets avaiable: Harr, Daubechies, Least Asymmetric, Best Localized, and Coiflet. User generated wavelets can be created by provided the low-pass decimation filter parameters in the constructor.

The DoubleWavelet type exposes the following members.

Constructors
 NameDescription
Public methodDoubleWavelet(DoubleWavelet) Creates a deep copy of the given wavelet object.
Public methodDoubleWavelet(WaveletWavelets) Creates a wavelet.
Public methodDoubleWavelet(Double, Double) Creates a wavelet from the given low-pass and high-pass decimation filters. If the orthonality condition for decimation filters h1 and h0,

Copy
h1(n) = (-1)^n h0(N - n)
is met, an orthogonal wavelet will result.
