MatLab: Classdef for polynomials error

I have written the following class for polynomials but i keep getting the error 

No public field polynomial exists for class Poly.

Error in Poly (line 13)
                obj.polynomial=struct('exponent',{p.exponent},'coeff',{p.coeff});

Here is my class

classdef Poly

    properties
        polynomial

    end

    methods
        function obj=Poly(p)
            if isa(p,'Poly')
                obj=p;
            else
                obj.polynomial=struct('exponent',{p.exponent},'coeff',{p.coeff});
            end
        end
        function answer=plus(obj1,obj2)
            obj1=Poly(obj1);
            obj2=Poly(obj2);
            answer=Poly(addPoly(obj1.polynomial,obj2.polynomial));
        end
        function answer=mtimes(obj1,obj2)
            obj1=Poly(obj1);
            obj2=Poly(obj2);
            answer=Poly(multPoly(obj1.polynomial,obj2.polynomial));
        end
        function answer=rem(obj1,obj2)
            obj1=Poly(obj1);
            obj2=Poly(obj2);
            answer=Poly(dividePolyrem(obj1.polynomial,obj2.polynomial));
       end





    end


end

I am unsure why I keep getting this error,I have tried adding (SetAccess=Public) after properties but that didn't seem to work. Any suggestions?

Your source code is fine (besides the missing end for classdef and methods), probably there is an exists an outdated version of the class, which prevents matlab to update the class definition. Clear all variables containing instances of Poly.
