When i insert my data and compute the result it appeared like this. How do i solve this issue? Im using a trial MathLab session.

>> X=Example1(:,1);

>> Y=Example1(:,2);

>> cftool

Hi @Hafawati Rosdi

Please check if a license exists for Curve Fitting Toolbox™. If a license exists, then the status returns 1.

status = license('test', 'Curve_Fitting_Toolbox')

[Steven Lord]

Even if they had a license for Curve Fitting Toolbox, the output of ver shows they don't have it installed and so would not be able to use functions from that toolbox (including cftool.)
