Note
MATLAB Command Window help entries use uppercase characters for the function and variable names to make them stand out from the rest of the text. When typing function names, however, always use the corresponding lowercase characters since MATLAB is case sensitive and all function names are actually in lowercase.

Help Menus and Help Buttons

In the figure window use the Help menu to access help for the Plot Editor, for MATLAB Graphics, and to access the Help Window and Help Desk. In the PrintFrame Editor window, use the Help menu to access help for editing printframes.

In the Page Setup dialog box and in the Plot Editor dialog boxes, click the Help button to access help for those dialog boxes.

On Windows platforms, in the Command Window, you can access the Help Window by selecting the Help Window option under the Help menu, or by clicking the question mark button on the menu bar. You can also access the Help Desk by selecting the Help Desk option under the Help menu.
