基于锁相环Top-down的建模方法在MATLAB环境下建立数字锁相环完整的仿真模型，并用SIMULINK对数字锁相环的仿真模型进行仿真。　(Top-down phase-locked loop based on the modeling method in MATLAB environment DPLL set up a complete simulation model, and use of digital phase-locked loop SIMULINK simulation model simulation.)

this file present one of the most popular way to calculate dijkstra distance presentation, especialy for 3D triangulation mesh.

INS GPS组合导航仿真程序，参考书就是亲永远的两本书一本惯导一本卡尔曼滤波(INS GPS navigation simulation program, reference is always pro two books an INS a Kalman filter)

滤波器程序，通过低通滤波器对数据进行滤波处理(Low-pass filter , mainly for time series filtering process .)

对于给定的贝叶斯网络和数据，寻找最可能的决策。 (Find the most likely decision given a Bayesian belief network and data )

说明：  在cmd介面實做出老鼠走迷宮，可從迷宮逃出(In the cmd interface really make a mouse Maze, escaped from the Maze)

说明：  通过编程实现通过共轭梯度法和Gauss-Seidel迭代法两种方法求解方程组(By programming through the conjugate gradient method and Gauss-Seidel iteration method for solving equations of two)

Basic shearing process in independent mode separable.

基本原理就是首先求解出连续系统微分方程的近似解，然后对系统的Jacobian矩阵进行QR分解，计算Jacobian矩阵特征值的乘积，最后计算出LE和分数维(The basic principle is to first find the approximate solution of differential equations continuous system, then the system will be on the Jacobian matrix QR decomposition product Jacobian matrix computing eigenvalues, and finally calculate the fractal dimension LE)
