I am working with https://pywavelets.readthedocs.io/en/latest/ in python.
For a project I am decomposing time-series with 33 points into approximation and detail coefficients.
The packages tells: len(cA) == len(cD) == floor((len(data) + wavelet.dec_len - 1) / 2)
Why is that way? Can someone explain to me how the formula above is derived?
Thanks in advance! Bram
