在MATLAB中从名称实例化类 [英] Instantiate class from name in MATLAB

问题描述

我试图列出我在Matlab文件夹中的某个文件夹中创建的类 - 仅使用他们的名字（类名）

I'm trying to list classes I created in some folder in my Matlab folder - using only their name (class name)

如果我知道它的名字是'SimpleString'

as an example, I have a class called 'SimpleString' - and I'm aiming to instantiate an object from that class, if all I know is that its name is 'SimpleString'

所以实时地，我想要从该类实例化一个对象。我想知道什么类是在一个文件夹（完成），然后能够实例化任何这些类（我的问题）
感谢

So in realtime, I'd like to find out what classes are in a folder (done), then be able to instantiate any of those classes (my question) Thanks

推荐答案

您可以使用

You can use eval to instantiate the class using just the class name.

instance = eval('SimpleString');

但是，如果你只是遍历包含类定义的文件夹中的所有m文件，抓取文件名，您将只能使用此方法调用默认构造函数。

However, if you're simply iterating through all the m-files in a folder containing class definitions and grabbing the file names, you'll only be able to invoke the default constructor using this method.
