Question

我将如何做（例如）这样的事情：

house = Building('blue'); % creates an object representing a 'blue' house 
                          % based on a class called building

room1 = Room('kitchen', 9);  % creates a room object representing a kitchen
                             %  with a size of 9 m^2  
room2 = Room('lobby', 5);    % creates a room object representing the lobby
                             %  with a size of 5 m^2  

house.add_room(room1);    % assigns the two rooms to the house object
house.add_room(room2);    %

house.room_count();       % should return the number 2
house.size('kitchen');    % should return the size of the kitchen, i.e. 9
house.size();             % should return the size of the entire house, i.e. 14
house.room_list();        % should return a list of the rooms in the house
                          %  which could e.g. be the string 'kitchen lobby'

这个例子完全是理论上的，我只是想知道如何在Matlab中实现这样的东西来看看语言是如何工作的。我会感激任何帮助。

我的背景是C ++的更“基础”语言，但我想学习Matlab。但是，我似乎无法找到解释这类事情的任何有用的代码示例;因此这个问题。

Answer 1

我不确定这是否完全符合您的所有要求，但您是否尝试过使用结构类？

Answer 2

如果您的背景是C ++，那么您应该熟悉类和对象的概念。

以下是实施部分设计的快速示例：

Room.m

classdef Room < handle
    properties
        name
        area
    end
    methods
        function obj = Room(name, a)
            if nargin < 2, a = 1; end
            obj.name = name;
            obj.area = a;
        end
    end
end

Building.m

classdef Building < handle
    properties
        color
        rooms
    end
    methods
        function obj = Building(clr)
            obj.color = clr;
            obj.rooms = Room.empty(1,0);
        end

        function add_room(obj, r)
            if ~isa(r, 'Room'), return, end
            obj.rooms(end+1) = r;
        end

        function num = room_count(obj)
            num = numel(obj.rooms);
        end

        function list = room_list(obj)
            list = {obj.rooms.name};
        end

        function sz = area(obj)
            sz = 0;
            for i=1:numel(obj.rooms)
                sz = sz + obj.rooms(i).area;
            end
        end
    end
end

现在我们可以像你一样创建对象：

house = Building('blue');
house.add_room(Room('kitchen',9));
house.add_room(Room('lobby',5));
house.room_count()
house.room_list()
house.area()

Matlab - 可以添加不同＆＃34;项目的类＃34;
