To customize display of your object, it is best practice to either subclass matlab.mixin.CustomDisplay or overload the disp function. It is rarely necessary to overload display.

MATLAB calls the display function whenever an object is referred to in a statement that is not terminated by a semicolon. If an assignment is made, the display function prints the name of the variable that is being displayed. Otherwise display uses ans as the variable name. The display function then calls disp to handle the actual display of the values. For more information, see Overload the disp Function.
