产生火炮发射炮弹的航迹，模型的建立，并画出仿真结果。(The track artillery shells fired generation, model, and draw the simulation results.)

惯导捷联式平台的应用，通过此平台来仿真计算星体的位置，各种姿态。(INS strapdown platform applications, simulation through this platform to the position of the stars, the various postures.)

读取激光雷达数据并计算消光系数廓线，作图(read lidar data and get extinction coefficient profile and figure)

ZEMAX是美国 Radiant Zemax 公司所发展出的光学设计软件，可做光学组件设计与照明系统的照度分析，也可建立反射，折射，绕射等光学模型，并结合优化，公差等分析功能，是套可以运算sequential及Non-Sequential的软件。(ZEMAX is a wonderful too for designing light .)

通过pch文件提取nastran质量矩阵、刚度矩阵，需要更改文件名称和自由度数（dof）,生成质量矩阵、刚度矩阵M,K(Extraction of mass matrix, stiffness matrix of NASTRAN)

说明：  关于混沌振子检测弱信号的系统相位变化图，对初学混沌的人很有用。(On the chaotic oscillator detection of weak signal system phase diagram, for beginners of chaos is very useful.)

PSO优化BP的源程序,加上作者的注释.(BP PSO optimization of the source, together with the author' s comments.)

This code is to find data distribution of wind speed. The Weibull distribution parameters are determined

多传感器数据融合的梯度下降法。方法较为简单，代码基本可以实现滚转角与俯仰角的解算，需要再调参数会更精确(Multi-sensor data fusion gradient descent. The method is simple, basic code can roll angle and pitch angle of the solver, you need to re-tune the parameters would be more accurate)
