Why do I get an error when using the "openExample" command in MATLAB R2023b?

When I try to use the "openExample" command in MATLAB R2023b, I encounter the following error:

Error using matlab.internal.examples.findExamplesXml
Unable to find "matlab/MatricesAndArraysGSExample". Check whether "matlab"
is the correct location for "matlab/MatricesAndArraysGSExample" and try
again.

Error in findExample (line 14)
examplesXml = matlab.internal.examples.findExamplesXml(component,arg);

Error in openExample (line 30)
metadata = findExample(exampleId);

There does not appear to be any indication of the actual issue, so how do I resolve it?

This error can occur when you have the "Documentation Location" in the MATLAB Help preferences set to “Installed Locally”, but you don’t have any documentation installed. 

There are two ways to resolve this error:

1. Verify whether the documentation is installed for the product containing the example. If not, then install the documentation. For more information see https://www.mathworks.com/help/install/ug/install-documentation.html
2. Change the help “Documentation Location” preference to “Web, on mathworks.com.” For more information see https://www.mathworks.com/help/matlab/matlab_env/help-settings.html
