D = ADDPROP(H,DynamicPropName) adds a dynamic property to the MATLAB
objects in array H. DynamicPropName can be a string scalar or character
vector. The added property is associated only with the objects of H.
There is no effect on the class of H. ADDPROP returns a
META.DYNAMICPROPERTY object, which can be modified to change property
attributes or add property set and get methods.
A dynamic property can be removed from an object by calling DELETE on
the META.DYNAMICPROPERTY object.
