matlab code for polyphase implementation

The additional argument (PeakD) is roughly the ratio of the typical peak width to the length of the entire data record. Small values detect fewer peaks larger values detect more peaks. It effects only the starting values for the peak detection parameters. (This is just a quick way to set reasonable initial values of the peak detection parameters, rather than specifying each one individually as in example 5.

说明：  用Matlab图形用户界面实现的计算器功能，简单实用(Matlab graphical user interface with the calculator function, simple and practical)

matlab时间序列分析，是进行matlab学习与研究进行的很好的东西，适合初学者学习(matlab time series analysis, is a good thing matlab learning and research, for beginners to learn)

本书为正在使用MATLAB的人士提供了100例精选的各种实例，为大家的学习和深造提供一些思路和帮助(This book is those who are using MATLAB provides various examples selected 100 cases for our study and studies to provide some ideas and help)

利用Kaiser窗设计一个低通滤波器，通带参数、阻带参数、阻带衰减、通带纹波都可以进行调整。程序简单易懂，按照凯塞窗设计滤波器的步骤，非常容易理解，得到的参数可以在MATLAB命令窗口中看到。(Kaiser window design using a low-pass filter, pass parameters, the stopband parameters, stopband attenuation, passband ripple can be adjusted)

说明：  小波去噪程序，在别人的程序上有一定的修改，对于任意声音文件a.wav进行小波去噪。(Wavelet denoising procedure, in others there are certain procedural changes, for any sound file a.wav wavelet denoising.)

语音信号处理来的预加重随后进行FFT变换，同时呈现结果图。(Speech signal processing preemphasis subsequent FFT, simultaneous presentation of the results in Fig.)

将复杂网络中的邻接矩阵数据，转换成两列数据，第一列表示有向网络的始点，第二列为末点(The complex network adjacency matrix of data, the data is converted into two, the first column represents the starting point of a directed network, the second column is the end point)
