public final class Wavelet3
extends MultiscaleFunction
implements Cloneable
Daubechies wavelets adapted to the interval by Meyer. Thanks to Pierre Vial for the filters.


Constructor Index

 o Wavelet3()
 o Wavelet3(int, int)

Method Index

 o clone()
Return a copy of this object
 o dimension()
Number of scaling functions at scale where this wavelet belongs.
 o dimension(int)
Given that the wavelet is written in terms of a scale containing dimension() scaling functions and going jfin scales ahead (iterating jfin times), tells you how many scaling functions you'll need.
 o equals(Object)
Check if another object is equal to this Wavelet8 object
 o evaluate(int)
Return as an array the sampled values of the function
 o getFilterType()
This method is used to compute how the number of scaling functions changes from on scale to the other.
 o position()
Tells you what is the number of this wavelet.
 o setParameters(int, int)
Set the parameters for this object
 o toString()
Return a String representation of the object

Constructors

                 int K)
 o Wavelet3
 public Wavelet3()

Methods

 o equals
 public boolean equals(Object a)
Check if another object is equal to this Wavelet8 object

Overrides:
equals in class MultiscaleFunction
 o toString
 public String toString()
Return a String representation of the object

Overrides:
toString in class MultiscaleFunction
 o getFilterType
 public int getFilterType()
This method is used to compute how the number of scaling functions changes from on scale to the other. Basically, if you have k scaling function and a filter of type t, you'll have 2*k+t scaling functions at the next scale (dyadic case). Notice that this method assumes that one is working with the dyadic grid while the method "previousDimension" define in the interface "filter" doesn't.

Overrides:
getFilterType in class MultiscaleFunction
 o setParameters
 public void setParameters(int N0,
                           int K)
Set the parameters for this object

Parameters:
N0 - number of scaling function on the scale of this object
K - position or number of this object
Throws: IllegalScalingException
if N0 is not large enough
 o clone
 public Object clone()
Return a copy of this object

Overrides:
clone in class MultiscaleFunction
 o evaluate
 public double[] evaluate(int j1)
Return as an array the sampled values of the function

Parameters:
j - number of iterations
Overrides:
evaluate in class MultiscaleFunction
 o dimension
 public int dimension(int jfin)
Given that the wavelet is written in terms of a scale containing dimension() scaling functions and going jfin scales ahead (iterating jfin times), tells you how many scaling functions you'll need.

Parameters:
jfin - number of iterations
Overrides:
dimension in class MultiscaleFunction
 o dimension
 public int dimension()
Number of scaling functions at scale where this wavelet belongs.

Overrides:
dimension in class MultiscaleFunction
 o position
 public int position()
Tells you what is the number of this wavelet. Wavelets are numbered from left to right with the one at the left boundary being noted 0.
