Using Help Functions

There are several help functions that provide different forms of help from the Help browser, or provide alternative ways to access help.

Function
Description
dbtype
Displays the M-file with line numbers. If you want to see only the input and output arguments for a function, use dbtype function 1, which displays the first line of the M-file.
demo
Displays the Demos pane in the Help browser, from which you can access demonstrations for the products you have installed.
doc
Displays the reference page for the specified function, block, or property in the Help browser. The reference page provides syntax, a description, examples, and links to related functions.
