Matlab Object-Oriented Programming learning notes (i) _matlab object-oriented programming learning notes

Hierarchical structure of code:

+foddername This is the package name and defines a namespace for its internal content

@classname This is the class folder, and the folder name is the class name

CLASSNAME.M this file as the primary class

FUNCTIONNAME.M this file as a class function file

You can place the keynote function on the outermost layer, which is parallel to the package name.

Main class Code structure

ClassDef (constructonload=true,sealed) myclock  
    in the command window enter t= myclock (8,30,20) Run program
    %constructonload=true, The constructor of the object is called when the class is loaded.
    Properties
        Hour;   % when
        Minute;    %
        Second;   % sec
    End
    methods
        function Obj=myclock (h,m,s)  % constructor
            obj. Hour=h;
            Obj. minute=m;
            Obj. Second=s;
        End
        function Show (obj)
            disp [Num2str (obj. Hour), ': ',...
                Num2str (obj. Minute, ': ', num2str (obj. Second)]);
        End
        Function value = Get. Hour (object)
            value = obj. Hour;
            Disp (' Querying Hour value ')
        end
        Function obj = set. Hour (Obj,value)
            if~ (value>0)
                error (' property value must is positive ')
            else
                obj. Hour = value;
            End
            disp (' Setting Hour value! ')
        End
        
    End

Properties define Variables

The

methods defines a method in which the same function as the class name is a constructor.
