將函數附加到Matlab結構

Question

是否可以將函數附加到類型爲struct的類屬性？用法：

% Definition: 
classdef a < handle 
    properties 
    bar 
    end 
    methods 
    function obj = a() 
     obj.bar = struct; 
     %obj.bar.attachFunction('apply', @someFunction); <-- something like this 
    end 
    end 
end 

% Usage: 
foo = a(); 
foo.bar.apply('test'); 
foo.bar.var1 = 1; 
foo.bar.var2 = 2; 

Answer 1

噢，那其實很簡單，只要我用了我的腦海。

classdef a < handle 
    properties 
    bar 
    end 
    methods 
    function obj = a() 
     obj.bar = struct; 
     obj.bar.apply = @(str) @obj.barApply(str); 
    end 
    end 
    methods (Access=protected) 
    function barApply(obj, str) 
     obj.bar.something = str; 
    end 
    end 
end 

foo = a(); 
foo.bar.apply('monkey'); 
foo.bar.apple = 2;
