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:
- 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
- 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
