On this page, the relevant information for you can be found in Step 4:
- For the Package a Toolbox tool to recognize custom documentation, include an info.xml file to identify your documentation files. If you use the builddocsearchdb function to build the documentation database before packaging your toolbox, you can include the generated helpsearch subfolder in your toolbox. The info.xml file and the helpsearch folder allow recipients to access your documentation through the Supplemental Software link at the bottom of the Help browser home page. For more information, see Display Custom Documentation.
- Alternatively, you can generate info.xml and helptoc.xml template files from the Package a Toolbox dialog box. To access your documentation through the Help browser, complete the documentation templates and include info.xml on the MATLAB path.
