How to get Dependent Property depending on properties of objects of different class
显示 更早的评论
See the code below:
Ex_ObjA.m-->
classdef Ex_ObjA
properties
a
end
methods
function Obj=Ex_ObjA(t)
Obj.a = t;
end
end
end
Ex_ObjBC.m-->
classdef Ex_ObjBC
properties
b
end
properties (Dependent = true, SetAccess = public)
c
end
methods
function Obj=Ex_ObjBC(t)
Obj.b = t;
end
function c=get.c(Obj,s1) % error: Get methods must have exactly one input
c = Obj.b + s1.a;
end
end
end
I tried to do following:
s1 = Ex_ObjA(2);
s2 = Ex_ObjBC(3);
s2.c
Not successful, because "Get methods must have exactly one input". So I can pass the s1.a to Ex_ObjBC to get s1.c?
Much appreciation!!!

There's no apparent reason why c should be a property, Dependent or otherwise. You could just write the class this way,
classdef Ex_ObjBC
properties
b
end
methods
function Obj=Ex_ObjBC(t)
Obj.b = t;
end
function out=c(Obj,s1)
out = Obj.b + s1.a;
end
end
end

Dependent properties are properties that you don't want to store actual data for. You do derive their values (in get() operations) on the fly from other properties, but class functions are also ways of deriving values from class properties (and other input). It's not clear why c should have property status in your application.

s2.getc(s1) is equivalent to getc(s2,s1)
