In Mathematica in wavelet package with the following codes
Phi[x_, j_, k_] := 2^(j/2) WaveletPhi[DaubechiesWavelet, 2^(j) x - k]
Phi for various values of $x,j,k$.
How does Mathematica do this computation?
My guess is cascade algorithm. If it is cascade algorithm, again how Mathematica does this computation because until now i have seen cascade algorithm just for $j=0$ and $k=0$.
If Mathematica does not use cascade algorithm what is the algorithm?
