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.)

当M=4时，QAM的蒙特卡罗仿真程序，绘出误符号率和误码率曲线，并和理论曲线比较。(When M = 4 Shi, QAM of the Monte Carlo simulation program, draw the symbol error rate and bit error rate curve, and and the theoretical curves.)

内容涵盖最优控制系统的设计方法，稳定性，稳态性能指标，动态性能等方面的详细分析(Detailed analysis covers the design of optimal control systems, stability, steady-state performance, dynamic performance)

基于maglab/simulink平台设计的利用duffing振子检测微弱正弦信号，非常好的一个源程序，自己亲自调试，运行在matlab2012b上没有问题，仿真步长0.01s,采用RK四阶算法。若有问题，欢迎指教(Based maglab/simulink platform using duffing detect weak sinusoidal oscillator signal, a very good source, personally commissioning, operation without problems on matlab2012b, simulation step 0.01s, using the fourth-order RK algorithm. If questions, please advise)

matlab 图像处理函数,所有相关函数应用示例。可作为工具查阅。(matlab image processing function, the function of all relevant application examples. Can be used as tools for access.)

说明：  通过拟合计算Qa，对较多的地理数据分析比较有用(By fitting the calculated Qa, geographic data analysis on more useful)

说明：  corner提取 corner提取 corner提取(corner from corner from corner extraction)

在MATLAB中利用FFT函数来进行变换，其中利用到了HAMMING窗(Using FFT function in MATLAB to carry out transformation, which used to HAMMING window)

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印(Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection)
