问题描述
我有一个带有相对复杂的数据树的结构.例如:
I have a struct with relative sophisticated data trees. for example:
class.data.head{1}.data2
我希望获得一个名为 data2_link 的变量，该变量与地址 class.data.head {1} .data2 链接，以便:
What I wish to get is a variable named data2_link to link with address class.data.head{1}.data2, so that:
(1)如果 class.data.head {1} .data2 有任何更改，它也会自动反映到 data2_link ，反之亦然.
(1) if there is any change on class.data.head{1}.data2, it will automatically reflected to data2_link as well, and vise versa.
(2)我不必键入长名即可访问 class.data.head {1} .data2 上的数据.
(2) I do not have to type the long name to access the data at class.data.head{1}.data2.
谢谢！
推荐答案
Matlab不支持引用.唯一的例外是handle，它允许引用对象.
Matlab does not support references. The only exception is handle which allows references to objects.
要使用它，data2必须是具有超类handle的对象，那么您可以简单地编写:
To use it, data2 must be an object with superclass handle, then you could simply write:
data2_link=class.data.head{1}.data2
请注意，面向对象的Matlab 明显减慢了您的代码，除非您使用Matlab 2015b或更高版本.
Note that object oriented matlab significantly slows down your code unless you use Matlab 2015b or newer.
