褶积程序，第一次用matlab编的，不知道能不能用(Convolution process, the first compiled with matlab do not know can not be used)

现需要在高度为600~700KM范围内，回归周期为30天的太阳同步轨道上布置一颗L波段的合成孔径雷达卫星。 1. 请设计合适的轨道参数，并仿真对应轨道下一个运行周期内星下点轨迹图（纬度和经度两个图）； 2. 计算多普勒中心频率，多普勒调频率与纬度的关系图（设姿态角为0°，天线视角20°~60°，推荐35°）； 3. 按高斯投影方式，将星下点轨迹图投影到地图坐标上。(Now requires a height of 600 ~ 700KM range, return period of 30 days are arranged on a sun-synchronous orbit L-band Synthetic Aperture Radar satellites. 1 Please design the appropriate orbital parameters and simulate the corresponding orbit within the next operating cycle nadir trajectories (latitude and longitude two graphs) 2. Calculate the Doppler center frequency, Doppler frequency and the relationship between latitude Figure (set attitude angle is 0, the antenna angle of 20 to 60, recommended 35) 3 Press Gauss projection, the nadir trajectories projected onto the map coordinates.)

说明：  简化了整个程序流程，在三维隐函数作图方面有较大的应用(It simplifies the whole program flow and has great application in drawing three-dimensional implicit function.)

MATLAB地震工具箱，包括地震勘探领域的常用算法，数据读取，剖面显示等(Seislab by matlab)

编写一通用的预测法分析程序，要求有一定的错误处理能力，出错后能够使程序继续运行下去，直到分析过程结束。可通过不同的文法（通过数据表现）进行测试。(Write a generic prediction analysis procedure that requires a certain degree of error-handling capabilities, enabling the program to continue after an error to run it until the end of the analysis process. Can be tested by different grammar (by performance data).)

ATC算法，多层多学科优化，特别好用，值得一试(ATC algorithm, multi-level, multidisciplinary optimization, particularly easy to use, it is worth a try)

自己编写的一个杆单元的程序，程序比较简单，大家多多指点！(I have written procedures for a rod element, the program is simple, you lot pointing!)

数学建模学习资料，建模方面详细讲解，是初学者学习建模的最佳选择(Mathematical modeling of learning materials, modeling to explain in detail)
