Simulink of describing function analysis of nonlinear control systems

i ask about if there is an official tool for describing funcion analysis of nonlinear systems?

i saw in some papers that there is a command (GetDF) or GenerateDescribingFunction but it doesn't work with me ?

if there are any tools belongs to Describing Function Method or any Nonlinearity analysis methods ?

Afaik, there is no official tool. Yes, well, I was facing the same problems the last days. The code contains errors, the pubisher has stated it himself: https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=1004015

Still, it wasn't that easy for me as a total beginner. Nevertheless, I got it working and attached the Simulink and Matlab files to this post, I hope this still helps a few months later, or maybe someone else struggling. Enjoy!

Cheers,
