How to solve this issue?Help me out?

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

[Nath]

classdef CEntity
     properties
        RandNumb
     end
     methods
         function obj = CEntity
         obj.RandNumb= InitArray12()
         end
     end
  end 
   function v=InitArray12()
         v=randi(100)
   end

The function InitArray12 is outside the classdef so it doesnt know the instance. Change it to return your values, and assign them in the constructor

[Cedric]

Are you sure that you want InitArray outside of your class definition? If so, Nath answered above; otherwise, you'll want to do something like:

 classdef CEntity

    properties
       RandNumb
    end

    methods
       function obj = CEntity()
          obj = obj.InitArray12() ;
       end
       function obj = InitArray12(obj)
          obj.RandNumb = randi(100) ;
       end
    end
 end

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
