I have been reading this PhD theis about wavelets and I am trying to reproduce some of the results but I don't know the specific code to use to generate similar results.
Then, the paper says:
The customer demand is transformed to the wavelet domain by the non-decimated wavelet transform performed with the Symmlet 8 filter. Figure 47 shows customer demand in the wavelet domain.
Can someone point me out how to reproduce this results using Python (then R, then matlab, in that order of preference)
