Hi, thanks for your answer.

According to this method of reply, I can make the data store memory as ramfunc type data. One of my questions is how to store the sub-system code as ramfunc type data，because I found out that subsystems can only inherit from models.

Hi, Venkatesh,thanks a lot!

I didn't see the drop-down option in your picture, may I ask what's wrong with it

Hi,

Can you please attach the model and update us on the version of MATLAB used.

Hi,

MATLAB version is R2019a, is that enough?

In addition, I think all the software used in MATLAB is the latest version, so what is the problem? what I need to do?

Hi,Venkatesh,

I am a user of academic edition. Is the use of this edition restricted? Or do I need to download some necessary components?

Hi,Venkatesh,

I have solved this problem,the Embedded Coder Dictionar seems can do the same work, and it's easy to implement this technology with following

Hi,Venkatesh,

I find it odd that once the Embedded Coder dictionary is opened, the memory sections of the Settings interface disappear？What's going on here?
