matlab时频分析配套源码第4章的程序，请大家共享(Matlab time-frequency analysis supporting source code, Chapter 4, please share)

建立一个实测信号的样本，这里我建立四个随机信号的样本，因为方便显示，蓝色信号为有用信号（正弦信号），黑色的四个信号是随机信号分别与正弦信号叠加形成的实测信号，最后红色的信号为样本的均值信号，即为时域同步平均效果下的信号。(A sample of the measured signal, I created four random signal samples, because it' s easy to display, blue signal is useful signal (sinusoidal signal), four black signal is a random signal with sinusoidal signal is superimposed on the formation of the measured signal. the final red signal is the mean of the sample signal, that is, the average effect of time-domain synchronous signal.)

蒙特卡洛算法的例程，包含所需的全部相关程序(Monte Carlo algorithm routine)

说明：  递归图（reecurrence plots），从相空间重构时间序列的matlab程序，(recurrence plots recostitution matlab code)

说明：  自己编写的有关计算过零率以及基音周期的函数(I have written the zero crossing rate and the calculation of a function of pitch period)

时延估计的WRELAX算法,自己做的，亲测可用(wrelax of time delay estimation)

说明：  海浪模拟 改变频率及其他参数输入得到不同的海浪谱(Common function set of MATLAB simulink)

基于多线程机制的，利用Matlab编写，粒子群优化算法。目标变量采用归一化处理，适用于所有的优化函数。优化函数自定义为fitness(x)。(Based on multi-threading mechanism, the use of Matlab to prepare, particle swarm optimization algorithm. Target variables using normalized treatment applies to all of the optimization function. Since the optimization function is defined as fitness (x).)

说明：  二维冲突概率算法，其实这个仿真是为了验证三维算法实现的基础，在二维的基础上再把二维扩展到三维。但也有不一样的地方(Two-dimensional conflict probability algorithm, in fact, this simulation is to verify the basis of three-dimensional algorithm, based on the two-dimensional two-dimensional and then extended to three-dimensional. But there are also not the same place)
