Added a new Toolbox but Matlab says I don't have it

39 views (last 30 days)
I paid for, and installed the Curve Fitting Toolbox. I confirmed that it is installed - the installer says it is all installed.
But in the Matlab UI, I get an error message when I try to use curve fitting functions. The error says - I need the Curve Fitting Toolbox!
Help!!

I might first quit out of MATLAB. Then restart it. Check again.
Next, does MATLAB show a license for it? What does ver tell you?
Finally, did it not get onto your search path? Using pathtool, look. If not, then add the top level directory for that TB onto your search path. Then save the search path.

Try
restoredefaultpath
If that doesn't fix it, either reinstall, or call tech support on Monday for free installation suppo
