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.

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.
