（7，4）系统循环码译码器 decode_out = cyclic_decoder(decode_in) 该系统循环码译码器的生成多项式是g(x) = x^3 + x + 1 输入参数decode_in是接收到的循环码字，是1×7的行向量；输出decode_out是解 码后的信息码字，是1×4的行向量。 函数运行时，同时画出接收循环码字和译出码字的波形图。 ( (7,4) system cycle Decoder decode_out = cyclic_decoder (decode_in) cyclic code decoder of the system generating polynomial is g (x) = x ^ 3+ x+ 1 input parameters decode_in is the received codeword cycle, the row is 1 × 7 vector output decode_out solution code is the information after the code word is 1 × 4 row vector. Function to run at the same time code word and draw a circle to receive the word of the translated code waveform.)

说明：  求解方阵所有的特征值以及特征值对应的特征向量(all eigenvalue and the corresponding eigenvectors for square matrix)

说明：  用matlab写的维纳滤波，最陡下降法的实现例程。(Matlab written by Wiener filtering, the steepest descent method to achieve routine.)

无周期伪随机码P码，该程序可即时产生长码，可以控制生成长度(P code)

说明：  rung-kutta 4 he inputs func, x0 and y0 define an IVP y = func(x,y), y(x0) = y0. This provides an approximation to y(x0:h:xn) using fourth-order Runge-Kutta method with step size h

DESCRIPTION: This Matlab algorithm performs many tasks associated with power system analysis. First, it has the ability to perform both fully coupled and dc power flow analysis. Second, it has the ability to create measurements (with user-defined error) to be used as input for state estimation. Third, it has the ability to perform state estimation - allowing the user to examine how the placement of measurement devices as well as magnitude of distibution of measurement error affect the discrepency between power flow and state estimation results. In essence, it provides the user with a complete package for the study of both power flow and state estimation in n-bus power systems.

在matlab的ui里创建滑动组件,具有交互式文件编辑框，标签等多种功能。(Creates a slider in a separate uipanel, with an associated interactive EditBox, and left and right labels showing the minimum and maximum values of the slider, respectively.Moving the slider automatically updates the textbox, and vice versa. Both slider movement and text edits will trigger (non-recursively) the callback of the slider.)

Kennard Stone 算法 用于数据集的划分（训练集 和 测试集） 算法同时输出训练集、测试集，以及训练集或测试集中样品在原数据集中的编号信息，方便样本的查找。 原始代码来源于本网，自行重新编译，如有需要，欢迎下载。 (Kennard Stone agorithm for the partition of data set (training set and test set) the outputs of the agorithm not only includes the training set and test set also the index of samples of training set or test set in the original data set,which make the search more convenient.)
