OOP derive comm.CRCGenerator

I try to derive the CRCGenerator of the comm toolbox.

See: sample code

classdef crc < comm.CRCGenerator

      properties (Nontunable)
          CRCName
      end

end

The result is, that the new property CRCName remains hidden in disp() but is shown in properties().

I'm using MATLAB Version: 7.14.0.739 (R2012a) and Communications System Toolbox Version 5.2 (R2012a).

>> a = crc(); >> disp( a );

a =

System: lte.generic.crc 

Properties:
         Polynomial: [16 12 5 0]
  InitialConditions: 0          
  CheckSumsPerFrame: 1

>> properties( a );

Properties for class lte.generic.crc:

    CRCName
    Polynomial
    InitialConditions
    CheckSumsPerFrame

I'm not a MATLAB class system expert, but I wonder if you need to overload DISP for your class. You could try that and see if it resolves the issue.

With the overloaded disp() function it works, thanks.

classdef crc < comm.CRCGenerator

        properties (Nontunable)
            CRCName
        end

        methods
            function disp( obj )
                 builtin('disp', obj );
            end
        end

end
