@folder和+ folder [英] @folder and +folder

问题描述

MATLAB中以下文件夹名称的含义是什么?

What is the meaning of the following folder names in MATLAB?

• @folder
• +folder

• @folder
• +folder

我创建了一个使用classdef语法的类Tata.m. 我应该将其放入@folder还是+folder?

I've created a class Tata.m which uses the classdef syntax. Should I put it in an @folder or a +folder?

我看过文档，但还不清楚 在哪种情况下应使用@folder，在哪种情况下应使用+folder.

I've looked at the documentation but it is not really clear in which cases the @folder should be used and in which cases the +folder should be used.

推荐答案

+folder部分是MATLAB软件包文件夹.如果将Tata.m放在类似+folder/Tata.m的位置，则MATLAB会将其称为类folder.Tata.如果将其放置在someOtherFolder/Tata.m或someOtherFolder/@Tata/Tata.m之类的文件夹中，则MATLAB会将其称为Tata.

The +folder piece is a MATLAB package folder. If you place Tata.m in a location like +folder/Tata.m, it will be known to MATLAB as the class folder.Tata. If you place it in a folder like someOtherFolder/Tata.m, or someOtherFolder/@Tata/Tata.m, it will be known to MATLAB as Tata.

将classdef文件放在类似@Tata的类目录中以使您可以将某些(或全部)方法的定义放在单独的文件中很有用.

It can be useful to place a classdef file in a class directory like @Tata to allow you to put the definition of some (or all) methods in separate files.

doc 具有更多细节.

要尝试弄清@目录:历史上，具有方法methodOne和methodTwo的类Tata将需要以下文件:

To attempt to clarify the @ directories: historically, a class Tata with methods methodOne and methodTwo would require the following files:

somePlaceOnThePath/@Tata/Tata.m
somePlaceOnThePath/@Tata/methodOne.m
somePlaceOnThePath/@Tata/methodTwo.m

在新"对象系统中，您仍然可以使用上面的布局，而无需进行修改.在另一个极端，您可以将Tata的整个实现放在以下单个classdef块中:

In the "new" object system, you can still use the layout above without modification. At the other extreme, you can place the entire implementation of Tata in a single classdef block in:

somePlaceOnThePath/Tata.m

如果您有一些大方法，或者想将类Tata的实现分成几个文件以简化并行开发，则可以使用这样的classdef:

If you have some large methods, or want to split up the implementation of the class Tata into several files to make parallel development simpler, you can take use a classdef like this:

%# somePlaceOnThePath/@Tata/Tata.m:
classdef Tata
    methods
         result = methodTwo(obj, arg)

         function methodOne(obj)
             disp('hello from methodOne');
         end
    end
end

还有

%# somePlaceOnThePath/@Tata/methodTwo.m:
function result = methodTwo(obj, arg)
% do stuff with obj and arg
end

严格来说，classdef中的methodTwo的高级声明是可选的，因为它使用的是默认访问说明符.如果您想将methodTwo用作私有方法，则可以将其放置在methods (Access = private)块中.

Strictly speaking, the advance declaration of methodTwo in the classdef is optional because it's using the default access specifiers. If you wanted to have methodTwo be a private method, you could place it in a methods (Access = private) block.
