leasqr() is well established for nonlinear regression and available in the optimization package for Octave.
You might be looking for a GUI to apply nonlinear regression.
FitToolNL() might help. Find links at
https://wiki.octave.org/wiki/index.php?title=Differences_between_Octave_and_Matlab&mobileaction
or on my web site at https://andreasstahel.github.io/Octave.html
Sorry for the obvious self reference.

I hope it helps

Feel free to post your question in your native language there.

In case this is about a bug in Octave: Could you please elaborate what that bug is? Maybe, a minimal example that fails, gives the wrong result, ...
