Hello,
I would like to try out the Airplane Tracking Using ADS-B Signals in Simulink example proposed from Matlab.
To test the example, this command has to be coppied in matlab :
openExample('comm/AirplaneTrackingUsingADSBSignalsInSimulinkExample')
But the following error occurs :
Error using findExample (line 35)
Example "AirplaneTrackingUsingADSBSignalsInSimulinkExample"
not found in "C:\Program
Files\MATLAB\R2020a\examples\comm\examples.xml".
Error in openExample (line 30)
metadata = findExample(exampleId);
I guess that the files for the example are missing, but i can't find the source code anywhere.

I found out how to access the example codes that are not available on the matlab website :
  • Open the "Add-on manager" in Matlab
  • Go to the "option" button, and open the toolbox documentation (Communications Tootlbox in my case)
  • Choose the section where your example could be in (Supported Hardware – Software-Defined Radio in my case)
  • The example codes are available using "Open Script"

Ran in:
Do you have Communications Toolbox installed? Check using the ver function.

When I write the ver function, I get this :

I already used some other examples such as BLE Channel Selection Algorithms, which has the same "Copy Command" button... But it works.
