Hello,

Based on the error message, I believe this issue might stem from two reasons:

For some reason, the curve fitting toolbox could have been removed from your MATLAB Path. Try the following steps

>> restoredefaultpath
>> rehash toolboxcache
%If this resolves the issue
>> savepath

Please perform a license test for the Curve Fitting Toolbox with the following command

license('test','Curve_Fitting_Toolbox')

If you are license to use the Curve Fitting Toolbox, the output of this command should be 1.
