Library for wavelet transformation

[erdemath]

Hello all,

I am looking for a library for wavelet transformation. In particular, I need to collect the respective wavelet transformation coefficients out of that library. I am not necessarily interested in wavelet transformation of a signal.

First, where have you looked for a library? Second, I'm confused: you say you want the coefficients, but aren't interested in transforming a signal. What coefficients are you expecting to get, if not those that you get from applying the transformation to a signal? Perhaps say what your end goal is (that is, what is the bigger picture in which this need has arisen?) and you might get better help.

To speak more scientifically, I will create a dictionary of wavelets per level of approximation. In other words, I will generate the coloumns of D in the
linear equation Dx = y, where x is the signal and y is its wavelet transformation. PyWavelets give me y, but I need D. Stanford university produced
such a library for matlab users, here https://statweb.stanford.edu/~wavelab/
