previousDimension

     public int previousDimension(int k)

  This method return the number of "scaling" functions at the previous scale given a number of scaling functions. The answer is always smaller than the provided value (about half since this is a dyadic implementation). This relates to the same idea as the "Filter type". It is used by the interface "Filter".

lowpass

     public double[] lowpass(double v[],
                             double param[])

highpass

     public double[] highpass(double v[],
                              double param[])

lowpass

     public double[] lowpass(double donnee[])

highpass

     public double[] highpass(double v[])

hat

     public static LinearSpline hat(int n0,
                                    int k)

scaling

     public static LinearSpline scaling(int n0,
                                        int k)

wavelet

     public static LinearSpline wavelet(int n0,
                                        int k)
