Reference page in Help browser
doc name displays documentation for the functionality specified by name, such as a function, class, or block.
If there is a MathWorks® reference page corresponding to name, then doc displays the page in the Help browser. The doc command does not display third-party or custom HTML documentation.
If there is no reference page corresponding to name, then doc searches for help text in a file named name.m. When help text is available, doc displays it in the Help browser.
If there is no reference page and no help text associated with name, then doc searches the documentation for name and displays the search results in the Help browser.
Display the reference page for the abs function.
Several products include different versions of abs. If your Help preferences support displaying documentation for those products, then the Help browser displays the MATLAB® abs reference page and a message with links to other versions of abs. This message appears at the top of the page.
Display the reference page for the handle class.
Display the reference page for the findobj method in the handle class.
Display the reference page for the Map class in the containers package.
Display formatted help text for a custom class.
MATLAB includes a set of example files that show how to create a class, including a class file named sads.m. Add the example folder to the path, and request documentation for sads.
addpath(... fullfile(matlabroot,'help','techdoc','matlab_env',... 'examples')) doc sads
Display the help for the steer method of the sads class.
Because the help text follows MATLAB conventions, MATLAB formats the display in the browser.
Name of a function, class, block, or other functionality, specified as a string. Alternatively, an operator symbol.
Some classes and other packaged items require that you specify the package name. Events, properties, and some methods require that you specify the class name. Separate the components of the name with periods, such as:
doc className.name doc packageName.name doc packageName.className.name
Methods for some classes are not accessible using the doc command; instead, use links on the class reference page.
