What shows up for

which -all fit

Also, do you have the Curve Fitting Toolbox installed and licensed?

[Osama Brinji]

C:\Users\osbri\Documents\UQ\optimization\fit.m

C:\Program Files\MATLAB\R2019b\toolbox\stats\stats\@gmdistribution\fit.m % gmdistribution method

C:\Program Files\MATLAB\R2019b\toolbox\curvefit\curvefit\fit.m % Shadowed

yes

You need to remove C:\Users\osbri\Documents\UQ\optimization from your MATLAB Path, or move it to the bottom of the path, or rename it to something else, as it is interfering with toolbox\curvefit\curvefit\fit.m being invoked when you ask to fit()
