Convert a Nested Struct to a Class
显示 更早的评论
Dear all,
I created a 3-layer nested structure in Matlab. Currently I name it as S. However, I will also need to have many variales with the same structure. I need S1, S2.....S100.
I realize that using class will be more helpful. If I have a class S_Class, my variables S1, S2.....S100 can be defined as:
- S1 = S_Class;
- S2 = S_Class;
Therefore, by using the class, I don't have to create the same structure for 100 times. Is my understaning correct?
If it is the case, how could I convert current 3-layer nested struct to a class?
Take the following code as an example
classdef S_Class
properties
V1
V2
V3
end
end
I would like V2 to be a stucture with several fields or even another structure inside. Is this possible?
Best regards,
Mingliang

Having lots of numbered variables is a sign that you are doing something wrong. It invariably leads to beginners writing code where they force themselves into writing slow, complex, buggy code that is hard to debug. Read this to know why:
"Therefore, by using the class, I don't have to create the same structure for 100 times. Is my understaning correct?"
It is not clear how the use of a class would mean that you do not have to create 100 class instances.

Class properties can be anything you want, including objects of other classes or arrays of objects of other classes. They can be structs if you really want, though if you are converting the top level to classes I would strongly recommend converting the rest to appropriate classes too.
Objects can be stored in an array just like doubles so an array of 100 objects makes a lot more sense than 100 individual variables, each of 1 object.
