Error in Simulink: Undefined function or variable 'uniqueOutput'
显示 更早的评论
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?

Are you trying to open a specific Simulink model? Are you encountered with this error when you open any model?
If you are encountered with this error while opening a particular model, check if the model requires definition of a variable/function named 'uniqueOutput'

I have the same problem, but It occurs with every model I tried to open so far and it is always the same 'uniqueOutput'.

I also have the same problem with a simulink protected block from the version 2017b. It says it cannot run the model as the variable/function 'uniqueOutput' is not defined. I tried to find where the variable is required and cannot find the place, and the solutions presented by the system don't solve anything. The problem is that I have 4 different versions of the model, and sometimes I can get one to work at first, but the second time it does not work.

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.

Anyone who could solve the problem withput moving files out from a web drive?

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).
Thanks
Hope it helps!!

Undefined function or variable 'uniqueOutput' in R2018b.
I tried with the mentioned suggestion and it didn't work.
Can anyone from MATHWorks help?
