说明：  matlab的中文帮助，对于学习matlab比较有用！(Chinese matlab help matlab more useful for learning!)

Stochastic resonance，SR）的概念最初是由Benzi等人提出并用于解释第四纪冰川问题，此后用于描述一种现象──非线性系统中内噪声或外噪声的存在可以增加系统输出的响应。这里一共有在网上下载的一共7种不同的程序，供大家分析参考(The concept of Stochastic resonance (SR) was first proposed by Benzi et al. And used to explain Quaternary glaciation. After that, it is used to describe a phenomenon -- the presence of internal noise or external noise in nonlinear system can increase the response of the system output. There are a total of 7 different programs available for download on the Internet for people to analyze and refer to)
