I want to go through the code to find out where variables are used in the model and what functions are available. Equivalent to the following operation is implemented using code.

Thanks for your help, I have found the answer to this question.

varObj = Simulink.VariableUsage(needcheckvar,'base workspace');
varsToImport =  Simulink.findVars('MyModel',varObj,'FindUsedVars','on');
varsToImport.Users

You can see which modules are used.

Note: "needcheckvar" can be char or cell.

Hi Fangping,

I understand you want to programmatically find where variables are used in a Simulink model.

This can be acheived using MATLAB's "find_system" function. This function allows you to search for models, blocks, lines, ports, and annotations directly from MATLAB scripts.

To know more about how to use "find_system" and the functional parameters that can be passed, you could refer to the below MATLAB's documentation.

Hello, I want to find out which modules of variables are used in the model, but the location of model attributes used by each module is not the same. Unless I know all of the attribute fillable variable names in advance, I can't find all the modules that use variables.

Hi @Fangping.

Well - maybe this is obvious ...:

"where variables are used"

type Ctrl-Shift-F which opens the "Find in files" GUI.

I have attached an image with the GUI and marked places you need to change/configure according to your needs

" what functions are available"

If you can open the file in Matlab editor - all you need to do is click on the "GoTo" button (see another attached image)

Good luck

There is no code that can be implemented, I want to replace the GUI operation by code, because the number I am looking for is relatively large.
