this program gives the idea about how image is represented in different plane in an 8bit mode.

在Matlab环境下运行function [d, RS] = fractal( x )即可。(In the Matlab environment to run function [d, RS] = fractal (x) can be.)

说明：  自己编写的使用ESPRIT算法进行信号频率估计的Matlab代码。(Matlab code of the ESPRIT algorithm for frequency estimation.)

三种无源滤波器输出波形比较分析，包括L型滤波器，LC型滤波器，LCL型滤波器(three kinds of filter)

The Frequency Domain Decomposition (FDD) is an output-only system identification technique popular in civil engineering, in particular in structural health monitoring. As an output-only algorithm, it is useful when the input data is unknown. FDD is a modal analysis technique which generates a system realization using the frequency response given (multi-)output data

recognition of handwriting that implement with matlab and neutral network.

poisson的PDF&CDF繪圖直接打開檔案RUN即可，生成圖像另有顏色標記(poisson' s PDF & CDF drawing RUN can open the file directly to generate the image and another color marker)

说明：  实现了snake without edge 这篇文献的算法。可以运行，而且结果良好。(snake 0r active contour model.)

（7，4）系统循环码编码器 code_out = cyclic_coder(code_in) 该系统循环码编码器的生成多项式是g(x) = x^3 + x + 1 输入参数code_in是信息码字，是1×4的行向量；输出code_out是编码后的系统 循环码字，是1×7的行向量。 函数运行时，同时画出输入信息码字和循环码字的波形图。( (7,4) cyclic code system Encoder code_out = cyclic_coder (code_in) cyclic code encoder of the system generating polynomial is g (x) = x ^ 3+ x+ 1 of information input parameters code_in code word is 1 × 4 row vector output code_out System is encoded codeword cycle, the row is 1 × 7 vector. Function to run at the same time draw the input code word and code word cycle waveform.)
