zernike 多项式的一部分程序，此程序用Matlab编写，能很好的实现功能(zernike polynomial part of the program, this procedure to prepare to use Matlab, can achieve a good functional)

说明：  计算循环卷积，DFT，IDFT,FFT... .. (Computing cyclic convolution, DFT, IDFT, FFT ... ..)

该文档中包含卡尔曼滤波的C++的实现源代码，并有详细说明。(The document contains the Kalman filter implementation of C++ source code and detailed instructions.)

The unified power quality conditioner (UPQC) is a custom power device, which mitigates voltage and current-related PQ issues in the power distribution systems. In this paper, a UPQC topology for applications with non-stiff source is proposed.

这个函数提供了一种基音频率检测算法，具体的算法内容详见MATLAB文件的说明，有详细的注释，工程中已经应用过，有较好的应用价值(This function provides a pitch detection algorithm, the specific content of the algorithm see MATLAB documentation, detailed annotations, engineering has been applied, has good application value)
