MATLAB includes a HELP facility that provides help on all MATLAB features. To access MATLAB’s help browser, click on the help button in the toolbar (this is the button with the ? symbol) or type doc in the command window. The help facility gives information on getting started with MATLAB and on using and customizing the desktop. It lists and describes all the MATLAB functions, operations, and commands.

You can also obtain help information on any of the MATLAB commands directly from the command window. Simply enter help followed by the name of the command. For example, the MATLAB command eig is used to compute eigenvalues. For information on how to use this command, you could either find the command using the help browser or simply type help eig in the command window.

From the command window, you also can obtain help on any MATLAB operator. Simply type help followed by the symbol for that operator. For example, to obtain help on the backslash operation, type help .
