有时候使用Matlab运行代码需要很长时间，又不想一直坐在电脑面前等程序运行结束。Matlab提供了一种发邮件的机制，能够在第一时间知道程序运行结束，让matlab在运行结束后，立刻通知我，这样就方便我立刻修改参数，继续运行。-Sometimes use Matlab to run the code takes a long time, don t want to have been sitting in front of a computer program is running over.Matlab provides a mechanism of email, to know the program runs in the first time over, let the Matlab at the end of the run, notify me immediately, so convenient I immediately modify parameters, continue to run.
