I have no cftool

I've just been given an exercise sheet to do of CFtool. I go on matlab and apparently it doesn't register this function? How do i get to use this tool if its not recognised?

Answer 1

[Wayne King]

cftool is in the Curve Fitting Toolbox. Should you have that in your installation? You have not told us anything about your installation.

Are you entering CFtool or cftool? cftool is the correct command.

Enter

>>ver

at the command prompt and see if you have the Curve Fitting Toolbox.

Enter:

>>license('test','curve_fitting_toolbox')

to see if you get a 1 returned.
