说明：  循环包络算法，用于计算信号的包络的一种方法(cyclic envelope)

给定一个音频范围内的模拟强噪声随机信号（强噪声+周期信号），将信号从强噪声中提取出来，并计算原信号及提取信号的均值、平均功率、方差、频谱及功率谱密度、互相关等 并附带图形(Given within the scope of an audio simulation of strong noise random signal (noise+ periodic signal), the signal from strong noise in the extracted and calculated signals and extract the original signal of the average, average, variance, spectrum and power spectral density , such as inter-related and incidental graphics)

人眼定位与人脸检测的程序，包含程序和仿真，效果不错！(code for Eye position and face detection , including procedures and simulation, the performance is good! )

对图形图像进行处理，使图形图像配准，更为准确(The graphic image processing, the graphics image registration, more accurate)

matlab VAR模型应用实例，附源代码和PPT(var model)

对比各种小波变换的效果，B为输入的原始数据，需要自己添加数据并设置为B(Comparative effects of various wavelet transform, B is the input original data, and the data they need to be added to B)

说明：  模糊综合评判计算程序 模糊综合评判的过程：1、灰色关联分析，求权重（程序见Relation）；2、模糊聚类分析，划分等级（程序见F_class）；3、隶属度计算，求隶属函数（程序见Subjection和subject）；4、模糊综合评判，计算各单元等级（程序见F_judge）。(Fuzzy comprehensive evaluation matlab code The process of fuzzy comprehensive evaluation: 1. Grey relational analysis to get weight (see Relation for program); 2. Fuzzy clustering analysis to divide ranks (see F_class for program); 3. Membership degree calculation to get membership function (see Subjection and subject for program); 4. Fuzzy comprehensive evaluation to calculate each unit grade (see F_judge for program).)

系统辨识的最小二乘辨识法，能辨识传递函数(Least squares identification system identification method can identify the transfer function)

AVI2Images 读取指定的AVI视频文件，并把视频帧依次写入图像文件。(AVI2Images reads the specified AVI video files and write video frames to the image files in order.)
