Good afternoon,
I can't understand why Matlab shows me this message: "Unrecognized function or variable 'dee' ".
I've got Simulink and it works, but when I write dee in the command window in order to work with the differential equation editor Matlab shows me this error.
What can I do?
Thank you

The command is not recognized by the system because this tool has been deprecated as of MATLAB R2020a. However, it is possible to use it by copying the necessary files (attached as a compressed folder) to the MATLAB path.

Thank you very much for your quick reply. Now the next question is: To which of the Matlab installation subfolders do I have to copy the files?

A colleague who is using version 2018b told me, that the dee folder is located at \MATLAB\'version'\toolbox\simulink\dee
I copied the files there but unfortunately the DEE still does not open and I only get the error I got before. Do I have to include this new folder somehow in Matlab and "tell" Simulink that (and where) it is available?
