Starting in R2012b, Simulink® models and videos that were previously called demos are now called examples. There are two ways to access these examples from the Help browser:
At the top of the product landing page, click Examples.
On any documentation page, click the Table of Contents button , and then select Examples.
You can filter documentation search results to display only examples.
For more information about changes to the Help browser, see the R2012b MATLAB® Release Notes.
