（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.)

这个程序是我做“化工过程综合与优化”课程设计时编写的。主要用于换热器设计的计算，含有注释。 (This code can be used to design the heat exchanger.)

这种方法一方面将像素的灰度值分散，可以分辨图象中比较细节的内容；另一方面，将图 象的灰度变化控制在一定范围之内，抑制了噪声的产生，较大程度上地保留了原始图象的亮度．(This approach on the one hand spread the pixel gray value, the more details you can identify the contents of the image the other hand, the image gray scale control in a certain range, suppress noise generation, a greater degree preserved on the original image brightness.)

说明：  matlab谱分析工具箱，作谱分析的很有用的工具，是基于matlab7.0的(Matlab Toolbox spectral analysis, spectral analysis for the very useful tool, is based on the matlab7.0)

this code is used to show the result of power flow solution of a power system
