说明：  QR二维码精定位，通过探测三个位置探测图形获得三个坐标，定位准确率90%左右。(QR code precise positioning, through the detection of 3 position detection patterns and then get 3 points, the recognition accuracy is about 90%.)

UNIX网络编程第2卷 进程间通信。学习Linux很好的书籍(UNIX Network Programming Volume 2 Interprocess communication. Good books to learn Linux)

说明：  this code is used to solve non linear equation using newtons method.

emd分解程序,可以分解得到多个符合条件的imf分量(It is emd.)

拉格朗日法实现多采样率的小数时延的实现，插值增加采样率，增加小数时延后，再以相同的速率抽取使其还原成原始采样率 (Lagrange method to realize the sampling rate of the realization of the fractional delay, interpolation increase the sampling rate, increase the decimal time delay, and at the same rate of extraction to make it back into the original sampling rate)
