I am getting the error below with every simulink model, I try to run on my computer. Even with the examples from the documentation. I also reinstalled Matlab and Simulink but but keep getting the error.

Undefined function or variable 'uniqueOutput'. Component: Simulink | Category: Model error

Does someone know, how to solve this problem?

I met the same problem and take the same action as you did, reintallisation doesn't work.

I finally solve this problem by moving the MATLAB running folder to the C drive. I used to run on the web drive, that doesn't allow the simulink to run.

Hi, same problem.

Definately seems to be a problem with models created in 2017b and used on other versions.

Hey,

The following steps may help in resolving the issue.

Under MATLAB Preferences > General settings, change the default path for the "Initial working folder" to be a known path (for example C:\Users\username\Documents\MATLAB or C:\temp).
