oot objectPurpose2root objectRoot object propertiesDescriptionSee AlsoThe root is a graphics object that corresponds to the computer screen. There isonly one root object and it has no parent. The children of the root object arefigures.The root object exists when you start MATLAB; you never have to create it andyou cannot destroy it. Use set and get to access the root properties.diary, echo, figure, format, gcf, get, setObjectHierarchyRootFigureAxesUicontrolUimenuUicontextmenuImageLightLinePatchRectangleSurfaceTextProperty ListThe following table lists all root properties and provides a brief description ofeach.
