Error with dee command

22 views (last 30 days)
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

Hi,
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.
Thanks.

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?

Sorry for asking again, no idea where exactly the files have to be copied or included?

You can unzip the dee.zip archive anywhere on your machine. Then, place the bottom folder 'dee' on the MATLAB path as shown below:
After that, run the command 'savepath' to save the setting permanently.
