求第一个城市到其它城市的最短路径.用矩阵（为顶点个数）存放各边权的邻接矩阵，行向量、、、分别用来存放标号信息、标号顶点顺序、标号顶点索引、最短通路的值(The first city to find the shortest path to other cities. With a matrix (for the number of vertices) records of the right side of the adjacency matrix, row vector, were used to store label information and label the vertex order, label the vertex indexes, the shortest pathway value)

适用于灰色预测的源代码 需要运用时可直接拷贝修改原来数据(Apply to the Grey prediction of source code to use when can copy directly modified original data )

产生常用的M序列，M序列是模拟以及仿真常用的序列。以及产生逆M序列。(M arrey)

根据系统的输入和输出，辨识系统的的传递函数。该系统为6阶系统，通过降阶降为2阶后，加入状态反馈和状态观测器，调整参数使2阶系统稳定，最后用于控制原6阶系统。阶跃响应和bode图效果都不错。(Based on the input and output of the system, the transfer function of the system is identified. The system is a 6 order system. After the order is reduced to 2 order, the system is added with the state feedback and the state observer, which adjusts the parameters to make the 2 order system stable. Finally, it is used to control the original 6 order system. Step response and Bode figure results are good.)

One of the most popular measurements of an ECG signal is the heart rate in this function we describes how to extract the R peak of a signal in order to analyze them in the "Regularity_Rythm" Function. The peak with the highest amplitude is called the R wave. An RR interval is the time that elapses between two successive R waves.
