Notes

Some Help browser features do not apply to demos:

• You cannot use the Search tab to look for words or code contained in the demos. You can use the Current Directory browser or lookfor function to search for code in M-file demo files.
• You cannot add most demos to the Favorites tab.
• The Product Filter does not apply to demos.
• You cannot select View -> Help View Options -> Page Source for some demos.

Function Alternative

To view the Demos in the Help browser, type demo in the Command Window. You can go directly to the demos for a specific product. For example

• demo toolbox signal
  

opens the Demos listing for the Signal Processing Toolbox.

To run one of the demos, you can type the demo name at the command line. For example, type

• vibes
  

to run a visualization demonstration showing an animated L-shaped membrane.

Running Playshow Demos.   To run playshow demos from the command line, type playshow followed by the demo name.

For example, if you type quake, the demo does not run. View the H1 line for quake.m, that is, the first comment line. It begins with two comment symbols (%%), indicating that quake is a playshow demo.

• %% Loma Prieta Earthquake
  

Therefore, type playshow quake to run the demo.
