Haar wavelet transform in Octave

I was trying to do wavelet transform in Octave. Found ufwt() function but couldn’t find Haar wave here. How can I use Haar wavelet transform in Octave?

The ufwt() function part of the ltfat-package. This package or the newer upstream version GitHub - ltfat/ltfat: This is an official development repository of LTFAT seems to not contain Haar wavelet transform.

After some web search, I found this project Matlab's tours - A Numerical Tour of Data Science, maybe it can be helpful :slightly_smiling_face:
