数学实验中用matlab完成的画图实验，应用matlab的很多仿真功能(Mathematics experiment with matlab finished drawing experiments, many of the matlab simulation function )

简单易懂的遗传算法，示例中是处理的无约束优化问题，可以为后续编程做参考(This is a simply genetic algorithm which can be used for further research.)

Welch功率谱密度是用改进的平均周期图法来求取随机信号的功率谱密度估计值。Welch法采用信号重叠分段、加窗函数和FFT算法等计算一个信号序列的自功率谱估计(PSD如上例中的下半部分的求法)和两个信号序列的互功率谱估计（CSD）。MATLAB信号处理工具箱函数提供了专门的函数PSD和CSD自动实现Welch法估计，而不需要自己编程。(method of power spectral density plot )
