在Matlab中每秒钟打印一次警告 [英] Print out a warning every whole second in Matlab

问题描述

我试图每秒钟打印一次警告或一条消息，例如已过去1秒". 有可能意识到这一点吗?

I am trying to print a warning or just a message after every second, like "1 second elapsed". Is there a possibility to realize that?

我用tic toc和循环尝试了它，但这还远远不够.而且，我永远也不会得到准确的一秒钟.是否有一个命令每X ms自动打印一次? 有什么想法吗?

I tried it with tic toc and a loop, but it is pretty insufficient. Furthermore I never get exactly one second. Is there a command that prints every X ms automatically? Any ideas?

谢谢.

推荐答案

使用计时器对象.

t = timer;
t.ExecutionMode = 'fixedRate';
t.Period = 1;
t.TimerFcn = @(~,~)disp('1s elapsed');
start(t)
