图像传输过程中，经常会受到各种噪声的干扰，本程序采用邻域平均法来减少噪声(In the process of image transmission, there will be various noise interference always,this program is to reduce noise base on Neighborhood average method. )

计算矩阵列向量的协方差矩阵,同时计算各列向量的均值(calculate the cov matrix)

模型预测控制，针对广义预测控制s函数的编写，(The writing of s function for generalized predictive control)

非常适合计算机视觉方面的研究使用,含噪脉冲信号进行相关检测,多抽样率信号处理。( Very suitable for the study using computer vision, Noisy pulse correlation detection signal, Multirate signal processing.)

the SOM training algorithm

说明：  对图像进行处理后常需要计算图像的PSNR值和NC值(calculate the PSNR and NC of pictures)

使用matlab产生混沌时间序列的源代码(use Matlab chaotic time series generated source code)

快速傅里叶变换 (FFT) 实现，给定信号x(t)=sin(2πf0t)，f0=50Hz，对x(t)以fs=200Hz进行抽样，抽样点数为N=16。编写程序实现对x(n)的快速傅里叶变换，求得相应的X(K)。(Fast Fourier Transform (FFT) to achieve a given signal x (t) = sin (2πf0t), f0 = 50Hz, for x (t) with fs = 200Hz sampling, the sampling points is N = 16. Procedures for the preparation of x (n) of the fast Fourier transform, obtained by the corresponding X (K).)
