Bayes辨识程序，系统辨识中应用，比较不错，希望大家能用到(Bayes identification procedures, the application of system identification, comparison is true, I hope everyone can use to)

用MATLAB 编写的图象纹理分析代码 (Prepared using MATLAB code image texture analysis)

说明：  对图像进行TA置乱，请根据图像大小自行设定周期。(TA scrambling the image, the image size according to set their own cycle.)

this file is source code for classify the digits by a perceptron neural network in Matlab platform.

基于MATLAB的例程 实现HUFFMAN编码算法 不定长编码 基于不同符号的概率分布(Variable-length coding based on the probability distribution of different symbols based on MATLAB routines to achieve HUFFMAN coding algorithm)

1.实验目的：绘制分形图案并分析其特点。  2.实验内容：绘制Koch曲线、Sierpinski三角形和树木花草图形，观察这些图形的局部和原来分形图形的关系。  3.实验思路：利用函数反复调用自己来模拟分形构造时的迭代过程，当迭代指标n为0时运行作图操作，否则继续迭代(1. Purpose: Draw fractal patterns and analyze their characteristics. 2. Experiment: Draw Koch curve, Sierpinski triangle graphic flowers and trees, observe the relationship between the local and original graphics fractal graphics. 3. Experiment idea: using the function calls itself repeatedly to simulate the iterative process when the fractal structure, when the iteration index n is plotted 0:00 run, otherwise continue iterating)
