Length of approximation and detail coefficients #586

Open bramDelft opened 3 years ago

bramDelft commented 3 years ago

Hi all,

First of all: thanks for this awesome package!

I am working with the approximation coefficients and the length is given by:

len(cA) == len(cD) == floor((len(data) + wavelet.dec_len - 1) / 2)

Is there any animation or explanation on the internet that describes the process in detail and explains the reason the length of the coefficient is as above?

If someone has a useful link/explanation, please let me know!

Best, Bram
