If I am reading it correctly ltfat has a wrapper wfilt_matlabwrapper.m but not the wfilters function which just calls wrappers from the matlab wavelet toolbox if present.

It is still in the stable branch of the signal package.

pkg install -forge signal  # it is with the latest package
pkg load signal
>> pkg list
Package Name  | Version | Installation directory
--------------+---------+-----------------------
     control *|   4.1.0 | ------------------
      signal *|   1.4.6 | ----------------
>> dwt([1 2 3],'sym4')
error: 'wfilters' undefined near line 52, column 16
error: called from
    dwt at line 52 column 14
>>


It should be removed from the repository completely.

Or Was there a reason to keep it?

My guess this function is abandoned / depreciated since most wavelet functions are in "ltfat" package ("ltft.org").

source :https://sourceforge.net/p/octave/signal/ci/default/tree/inst/dwt.m

line 52 - wfilters is not defined anywhere .No information is available about this octave function .

52      [Hp, Gp] = wfilters (wname, "d");


Because of this first calling sequence is not working.And this function has no tests.

Thank You
