Hi Denise Zin,

I understand that you are not able to use the ‘Curve Fitting Toolbox’ functions.

This is possibly because of missing other required toolboxes. Try following troubleshooting steps,

• ‘logncdf’ function requires ‘Statistics and Machine Learning Toolbox’, check If you have installed this toolbox. You can use the below command to get the list of installed toolboxes.

addons = matlab.addons.installedAddons

• If the ‘Statistics and Machine Learning Toolbox’ is not in the list, then you have to install this toolbox. To install the toolbox, you can use Add-On Explorer,

a. Open Add-On Explorer

b. In the search box, type ‘statistic and machine learning’.

c. Open the first result and select ‘install’ option

• If you don’t have licence to ‘Statistics and Machine Learning Toolbox’ alternatively you can use the custom function given in the following MATLAB Answer :- https://in.mathworks.com/matlabcentral/answers/1902695-problem-with-undefined-function#:~:text=An%20alternative%20without%20the%20toolbox
• The toolboxes are usually installed in predetermined default directories. If the Search path is changed or the toolbox cache is corrupted, then the MATLAB cannot find the toolboxes and will think the toolboxes are not installed. Repair the ‘Search path’ by using following commands.

restoredefaultpath
rehash toolboxcache
