S变换的matlab源码，并应用几个信号作为例子来说明怎么使用s变换以及s变换可以用来做些什么事情。s变换是时频分析领域中一个较新的内容，现在在信号处理，地震勘探，语音识别等领域都开始了对它的应用研究，是目前的一个热点。-S transform matlab source, and apply some signal as an example to illustrate how to use s and s transform transform can be used to do things. s transform time-frequency analysis are a relatively new area of content, now in the signal processing, seismic exploration, speech recognition and other areas of the beginning of its applied research, is a hotspot.
