Asked by Arun Badigannavar on 8 Mar 2013
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

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

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
