Matlab-定时器

场景一：每隔一段时间发送一次消息

t = timer;
t.TasksToExecute = 5; % 发送消息的次数
t.Period=1;% 发送消息的间隔
t.ExecutionMode='fixedSpacing';
t.TimerFcn=@takeBreak;
start(t)

function takeBreak(~,~)
    disp('你好！');
end

场景二：到达某时间点发送消息

t=timer;
set(t,'TimerFcn',@sendmessage,'Period',1,'ExecutionMode','fixedSpacing');
start(t);

function sendmessage(hobj,~)
    T=datestr(now,'HH:MM');
    if strcmp(T,'19:25')
        stop(hobj);
        delete(hobj);
        disp('你好！');
    end
end
