The curve fitting tool won't open when using the cftool command or when clicking on Curve Fitting in Apps. There is also an error message.

That's my code:
xvals = (-20:1:20)';
yvals = xvals.^2;
plot(xvals,yvals,'.','MarkerSize',20)
cftool(xvals,yvals)
Which gives me an error message:
Warning: Error occurred while executing the listener callback for event FitAdded defined for class sftoolgui.FitsManager:

Strangely, when I use the command f=fit(xvals,yvals,'poly2') it works. Why does the curve fitting toolbox doesn't open?

Hi Luca,
It seems you have used script name as any of the MATLAB function. Try to rename the script (other than MATLAB keyword) and run it again.
