oop – 如何使抽象依赖属性起作用

classdef A
    properties (Abstract = true)
        Valid;
    end
end

像这样的这个接口的实现

classdef B < A
    properties (Dependent = true)
        Valid;
    end
    methods
        function v = get.Valid(obj)
            v = 1;
        end
    end
end

但是当我尝试制作B的实例时,我得到以下错误

>> c = B()
??? Error using ==> B
The property 'Valid' restriction defined in class 'B' must match the property definition in base class 'B'.

谁能告诉我我做错了什么？

classdef A
    properties (Abstract = true, Dependent = true)
        Valid;
    end
end

根据documentation：

Concrete subclasses must redefine abstract properties without the
Abstract attribute set to true

我理解这一点的方式,子类属性属性必须与基类匹配(没有Abstract属性)
