ASN.1解析解码工具,可以解析各种ASN.1格式的文件,并对相应的BER文件解码(ASN.1 decoding analytic tools that can resolve all kinds of ASN.1 format files, and file decoder BER corresponding)

对AR（4）模型的经典功率谱估计，并与真实功率谱作比较。采用了welch方法，协方差法，burg方法(For AR (4) model of the classic power spectrum estimation, and with true power spectrum for comparison. Welch method using covariance method, burg method)

说明：  进行小波分析，得到更好地结果，画出较为精准的图像(Wavelet analysis was performed)

entropy and image encryption

说明：  一个4阶的切比雪夫Ⅰ型低通滤波器，可以用它对信号进行滤波。当然，滤波器的零极点图也是必不可少的。(A 4-order Chebyshev low-pass filter of type Ⅰ, you can use it to filter the signal. Of course, the filter pole-zero map is essential.)

用matlab实现hough变换的直线检测,对原有代码的错误指出进行了改正,可以直接运行.(using Matlab achieve hough transform linear detection, on the original error code that the correction can be run directly.)

关于二进制线性编码的程序，研究了它的功率频谱图 (About binary linear codes of procedures, the study of its power spectrum diagram)

DIN Power measurement Theory in Matlab/simulink

This function model the troposphere based on the inputs of the user: it adds clouds, fog,cirrus, wet air and dry air

matlab程序，用于人脸识别的K均值算法程序，非常有用。(matlab program for K-means algorithm for face recognition program, very useful.)
