DEE in R2020a

Is there DEE block in Simulink of matlab R2020a version? And how to open it? Type in command window dee + enter? its not working for me

It crazy that nowhere any information about DEE block could be found. Its like super secret block...

It is true that Differential Equations Editor was an undocumented demo tool. We removed it from the MATLAB/Simulink installation in R2020a. You can download the files here:

OK if someone made decision to remove DEE I suppose this guy should have a suggestion what to use in simulink instead of DEE? So what matlab stuff can suggest?

[Stefanie Schwarz]

Hi Vygandas, this has never been an official feature of MATLAB/Simulink so there is no direct replacement for it. If you would like to keep on using the tool, you can just download it from above link :)

So how to implement in simulink model based on differential equations?
