exp_mckenzie2022 contains unused code which seems to need additional toolboxes. Check if this code (and the toolbox) can be integrated in the AMT and then either integrate or remove. As it seems the integration process has been started but never finished...
also remove the "fit" which creates a dependency on the Curve Fitting Toolbox...
and remove the local functions in mckenzie2022, those which seem to be used just once.
