Accessing object B properties outisde of object A's getter method

I am trying to implement an object with dependent properties and therefore have a getter method to dynamically access these properties. However, I am having trouble with implementation once the properties are dependent on properties of objects outside of the particular class. EX
classdef objA
properties (Dependent)
propA
end
methods
propA = get.propA(objA)
propA = objA.propA * propB.value;
end

Sounds like your class objA should define a property that holds the object(s) you need to define your get operation.
classdef objA
properties (Dependent)
propA
propB
end
methods
propA = get.propA(objA)
propA = objA.propA * propB.value;
end

Thank you for the response. I had previously considered your suggestion however, what if propB is truly a property of some other uniquely different class. Ex: if objA.propA = tire.weight & objB.propB = door.weight. ( This is probably a bad example compared to the early given code)
