how to open curve fit tool in R009b?

When I try opening the curve fitting tool (i.e., I enter "cftool"), I get the following error: ??? Undefined function or variable 'cftool'. How do I open this tool so that I can work with data? Thanks, Terry

Are you sure you have the Curve Fitting Toolbox? Try typing 'ver curvefit'.
