Thank you for reporting this issue. I was able to reproduce the issue in R2023a. Below are results from MATLAB R2023a Update 5 installed in my machine.

>> openExample('driving/ExploreVirtualMCitySceneExample')
Error using matlab.internal.examples.copyFromWeb
Unable to download - MATLAB:webservices:HTTP404StatusCodeError. \nCheck your internet connection or change your Help preferences to view the locally installed documentation.
Error in matlab.internal.examples.copyFile (line 13)
    copied = matlab.internal.examples.copyFromWeb(component, folder, file, target, compressed);
Error in matlab.internal.examples.setupSupportingFiles (line 57)
        matlab.internal.examples.copyFile(f.componentDir, folder, f.filename, target, false);
Error in setupExample (line 21)
metadata = matlab.internal.examples.setupSupportingFiles(metadata, workDir);
Error in openExample (line 30)
[workDir,metadata] = setupExample(exampleId, workDir);

Can you please reach out to Technical Support and report the issue?

Meanwhile, the issue is not reproducible in R2023b. Can you use R2023b for a temporary workaround?

Hi Seongjae,

I understand that you are unable to access the ‘ExploreVirtualMCitySceneExample’ example in MATLAB.

I was able to reproduce the issue in the MATLAB R2023a version and found that the example is not accessible from the web version of documentation.

As a workaround, you can access the example by changing the help preferences to view the locally installed documentation as follows:

1.Navigate to the ‘Preferences’ option in the ‘Environment’ tab:

2. Modify the help preferences, to view the locally installed documentation, as shown below:

If the required documentation is not installed locally, you can do it by clicking on the ‘Install Documentation’ button and selecting the required toolbox.

Hope this helps!
