guassian sobel filter for image processing

霍夫曼编码,在图像处理中可以用来对取整后的数组矩阵进行编码，从而减少数据量(huffman encode)

说明：  这个是语音信号处理里面的基于MMSE的谱减法增强处理程序，此种方法是我见过消除噪声最好的！(This is the speech signal processing inside the MMSE-based spectral subtraction to enhance handling procedures, this method is the elimination of noise, the best I' ve ever seen!)

说明：  用于结构在动力荷载作用下的时程分析,地震荷载，随即荷载均可，采用newmark方法。(time-domain analysis of a linear strucutre under dynamnic loads。 Newmark method is used.)

说明：  关于MIMO weichselberger 的文档描述，主要有建模过程及方法，参数评定(Documentation on the MIMO weichselberger description of the main modeling process and methods, parameters assessed)

雷达模糊函数、模拟距离模糊函数，多普勒模糊函数，用多种视图显示模拟结果。(Radar ambiguity function, analogue distance ambiguity function, the Doppler ambiguity function, using a variety of view shows the simulation results.)

高端的离散时间傅里叶变换计算当然是你必不可少的需要(Discrete-Time Fourier Transform Computation )

A major issue in computer network is to prevent important information being disclosed to illegal user.

说明：  函数求导函数文件定义以及无线通信技术相关实现(function define of derivative)

  Matlab中如何求一个序列的极值？在Matlab中有专门求序列最大值和最小值的函数，分别是Max  和  Min，但是有时候我们不满足于求整个序列的最值，而是对序列的极值，也就是局部的最值感兴趣。对于解析函 数，这个比较简单，只要令一阶倒数为零求出对应的自变量就行了。(Matlab how to seek a extremum sequence? In the Matlab there is a special function for sequence of maximum and minimum values, respectively is Max and Min the value, but sometimes we do not meet for the whole series, but the extremum sequence, also is the value of local interest. For analytic functions, this is relatively simple, as long as the countdown to zero order and related variables on the line.)
