里面包含了随机矩阵理论里经典的仿真，如marcenko-pastur law,tracy-widom law等(It contains some classical simulationa in the random matrix theory，such as marcenko-pastur law,tracy-widom law)

万有引力单目标优化算法，用于单目标线性规划问题(Universal gravitation single objective optimization algorithm is used for single target linear programming problem.)

这是ansys里面apdl语言，用于计算圆柱体开裂(This is the ansys inside apdl language, used for calculating the cylinder craze)

说明：  FFT，整型数据代替浮点型数据 本程序是搜集资料并加上自己的分析，整了很长时间才测试通过的FFT程序，运行时间和所占内存方面都比较满意。(FFT, integer data instead of floating point data This program is to collect data and add their own analysis, the FFT program passed the test for a long time, the running time and memory occupied are relatively satisfactory.)

说明：  实现粒子滤波。包含运行模型，测量模型，重采样和归一化(Implement particle filter. Including operation model, measurement model, resampling and normalization)

应用MATLAB编写的偏最小二乘法程序,且具有画图功能(MATLAB prepared by partial least squares procedure, which is drawing functions)

Code source of Finite Element Analysis with Error Estimators

高超声速飞行器上升轨迹优化计算。采用勒让德伪谱法直接优化方法。(trajectory optimization of hypersonic craft program with legendre method)

己知一些离散的点，使用matlab利用最小二乘法拟合(Had a number of discrete points, with linear least squares fitting)

这是用于将格点数据转化站点数据的fortran程序，比较详细，可以画图(This is a fortran program for the grid data into the site data in more detail, you can draw)
