刚度矩阵集成的程序，使用matlab编制，上传的是m文件(GridAssemble)

薛定宇《高等应用数学问题的MATLAB求解》，也是matlab对于高等应用数学的应用，适合进阶学习(Xue Dingyu Higher Applied Mathematics MATLAB to solve, matlab for Higher Applied Mathematics for Advanced Learning)

连接各路口节点，统计道路条数，求出各道路的长度，并求出所有顶点对间的最短距离(Connect each node of the intersection, statistics, road number, find the length of the road, and calculated the shortest distance between all vertices)

利用经典Jakes模型生成时间频率双选信道，自己写的，已对各参数进行标注(Using the classical Jakes model to generate time-frequency dual-channel selection, write, and has marked the various parameters)

非线性扩展卡尔曼滤波算法的matlab程序(Description:This is a tutorial on nonlinear extended Kalman filter (EKF). It uses the standard EKF fomulation to achieve nonlinear state estimation. Inside, it uses the complex step Jacobian to linearize the nonlinear dynamic system. The linearized matrices are then used in the Kalman filter calculation. The complex step differentiation seems improving the EKF performance particularly in accuracy such that the optimization and NN training through the EKF are better than through the UKF )
