SCDF(S, 2, 2, L, 3): Example 2: S = [8, 7, 6, 5, 4, 3, 2, 1]




Problem
  
This post is a detailed example of computing individual elements of SCDF(S, 2, 2, L, 3) at each of the three scales on S = [8, 7, 6, 5, 4, 3, 2, 1]. SCDF(S, 2, 2, L, J) notation is defined here. This notation is based on the notation introduced in Chapters 3 and 4 in "Ripples in Mathematics" by A. Jensen & A. la Cour-Harbo.



SCDF(S, 2, 2, 1, 3): Scale L = 1
  
Figures 1 and 2 show the formulas for the elements of S and D at scale L = 1. Figure 3 shows an example of computing the first scale of the signal S = [8, 7, 6, 5, 4, 3, 2, 1].

SCDF(S, 2, 2, 2, 3): Scale L = 2
  
Figure 4 shows the individual formulas for S and D at scale L = 2. Figure 5 shows the computation of individual elements of S and D of the sample [8, 7, 6, 5, 4, 3, 2, 1] at scale L = 2.

SCDF(S, 2, 2, 3, 3): Scale L = 3
  
Figure 6 shows the individual formulas for S and D at scale L = 3. Figure 7 shows the computation of individual elements of S and D of the sample [8, 7, 6, 5, 4, 3, 2, 1] at scale L = 3.

Summary of SCDF(S, 2, 2, 3, 3) at All Three Scales
  
Figure 8 summarizes the three scales of SCDF(S, 2, 2, 3, 3), where S =  [8, 7, 6, 5, 4, 3, 2, 1] .
