classdef CEntity
     properties
        RandNumb
     end
     methods
         function obj = CEntity
         InitArray12()
         end
     end
  end 
   function InitArray12()
         obj.RandNumb=randi(100)
   end
How to send value which is calculated in the "InitArray12" function to "RandNumb" which is there in the properties

Best Answer

Or this way

    >> ce = CEntity()
    ce = 
      CEntity
      Properties:
        RandNumb: 92
      Methods
    >>

where

    classdef CEntity < handle
        properties
            RandNumb
        end
        methods
            function obj = CEntity
                InitArray12();
            end
            function  InitArray12( obj )
                obj.RandNumb = randi( 100 );
            end
        end
    end

MATLAB: How to override inherited methods

You can't do what you asked. If you could, you could relax the property setting validation to the point where your subClass instance wouldn't be a valid superClass instance.

You may be able to do what you want, however. Your superClass's property setter could call a normal instance method that subClass could overload. See the trustedSubclassSetterHelper methods in the attached superClass495080 and subClass495080. That helper doesn't actually set the property (otherwise you get into a loop) but merely provides the updated value. This means that the value would have to be something both superClass495080 (in set.prop1) and subClass495080 (in trustedSubclassSetterHelper) accept as a valid value.

>> Q = superClass495080
Q = 
  superClass495080 with properties:
    prop1: 'Hello!'
    prop2: 'My name is'
>> Q2 = subClass495080
Q2 = 
  subClass495080 with properties:
    prop3: 'Dom.'
    prop1: 'Hello World!'
    prop2: 'My name is'

MATLAB: MATLAB OOP question.

In MATLAB, a method would typically have a signature:

 classdef test1234 < handle
    properties (Access = public)
     prop
    end
    methods 
    function obj = test1234()
        obj.prop =0;
    end
    function AddOneToThatThing(obj)
         obj.prop = obj.prop+1;
    end
    end
end

Then

      a = test1234;
      a.AddOneToThatThing();
      a

Gives you what you need. The key here is Handle classes
