命令模式(Command)将命令封装为对象，实现命令发送者和命令接收者的解耦。线程池、MVC框架用到了命令模式，本文根据以下类图，用matlab实现命令模式。
Invoker.m (传递命令对象Invoker：持有命令对象，要求命令对象执行请求)
classdef Invoker < handle
properties
command
end
methods
function setOrder(obj,command)
obj.command = command;
end
function execute(obj)
obj.command.execute();
end
end
end
Command.m (抽象命令接口Command：定义命令的接口，声明执行的方法)
classdef Command < handle
methods(Abstract)
execute(obj);
end
end
ConcreteCommand.m (具体的命令对象ConcreteCommand：持有具体的接受者对象，完成具体的具体的命令)
classdef ConcreteCommand < Command
properties
receiver
end
methods
function obj = ConcreteCommand(receiver)
obj.receiver = receiver;
end
function execute(obj)
obj.receiver.execute();
end
end
end
Receiver.m (接受者对象Receiver：接受者对象，真正执行命令的对象)
classdef Receiver < handle
methods
function execute(~)
disp("Receiver execute");
end
end
end
test.m
r = Receiver(); c = ConcreteCommand(r); i = Invoker(); i.setOrder(c); i.execute();
