Display format for empty object arrays




displayEmptyObject(obj) is called by disp when obj is an empty array. An object array is empty if one or more of its dimensions are zero. Override this method to customize the display of an empty object array.

The default display of an empty object consists of a header and a list of property names. The header shows the object's dimensions, and the properties are listed in the order defined in the class definition. displayEmptyObject shows only those properties with GetAccess set to public and Hidden set to false.

An empty object array is not scalar. MATLAB® does not call displayScalarObject on empty arrays regardless of their dimensions.

Input Arguments
