说明：  矩形波函数，计算其频谱，幅度谱和相位谱，与理论值比较。(Rectangular wave function to calculate the frequency spectrum, amplitude spectrum and phase spectrum, compared with the theoretical value.)

这是对音频新训好进行bch编码后加入噪声的程序(This is the new audio training good for BCH joined noise coding procedures)

两个正态总体的均值T平方检验程序，大家可以看看参考下(T square test for two normal sample)

检验Rossler混沌系统在有限时间内具有鲁棒性(Inspection Rossler chaotic system in the limited time robust)

matlab提取图像质心和主轴，使用的是matlab图像处理工具箱函数(extraction matlab image centroid and the spindle, using matlab image processing toolbox functions)

说明：  这是一个关于图像边缘检测的小程序，希望对大家有所帮助(This is an image of a small edge detection procedures, we hope to help)

北大高慧璇版《应用多元统计分析》第4章4回归分析MATLAB编程源码(Applied Statistical Analysis )

通过计算短时信号熵，与阈值比较，得到判决结果。并采用顺序统计滤波器（最大值滤波器）对所得熵值滤波，提高判决精度。 能有效的分辨出语音信号和噪声信号，且通过后端平滑处理，使语音检测结果更加集中。(VAD based on short-time entropy, precision improved by using order-statistical-filter, VAD result is smoothed to make the result more accurate.)

用Matlab实现人脸图像分割的程序，可以使用(Implementation of a Face with Matlab segmentation procedure, you can use)

三次样条插值的源程序，程序稍稍长了点 希望大家能用到(cubic spline interpolation of the source, procedures slight hope everyone can wait to)
