一个例子chaos，很好的东西哦，没有什么什么不会做的了，混沌太美了(An example of chaos, something good Oh, no, what will not do, the chaos is too beautiful)

本组设计的声音导引系统使用双MCU结构，采用基于时间差的声源定位算法（利用三路接收器的时差信号）结合PID算法判断并控制移动声源的速度。本设计的特色在于使用四阶Butterworth带通滤波器对声音信号进行处理，使其具有较强抗干扰能力。且系统设计性价比高，功耗低。(Our group design the Sound Guidance System based on Bi-MCU configuration, using time difference sound source orientation arithmetic（the time difference signal from three receivers）combining PID arithmetic to determine and control the mobile sound source’s velocity. The feature of the designation is processing the sound signal by four-order Butterworth band-pass filter. This enhances the anti-jamming ability. Furthermore, the system has the high performance and low price.)

Myplotyy情节不同的数据集具有共同的X轴使用一个数字，但个别的Y轴。 每一个曲线（Y轴）的属性可单独调整，为线性或对数尺度，正常或反向规模，置信区间等，颜色，曲线标签，... 见截图和运行示例“myplotyy_example.m”在zip文件中。 (Myplotyy plots different data sets with a common x-axis but using individual y-axes in one figure. The properties of every curve (y-axis) can be individually adjusted, such as linear or logarithmic scale, normal or reverse scale, confidence intervals, colors, curve labeling, ... See screenshot and run the example "myplotyy_example.m" included in the zip-file. )

QPSK modulation in Rayleigh channel

The network weights are adjusted during the online implementation. The method used is based on the gradient descent method (GD), which is a simple and fast method for online adaptation.
