这是求解线性规划问题的revised simplex method的算法，需要得知原始的基和基本解(This is the revised simplex method for linear programming problem. It needs the initial basis and basic solution for input.)

变分模态分解的python版本，个人根据MATLAB版本译制而成(Python version of variational mode decomposition)

Lasso算法源代码,stanford开发的,绝对可靠(Glmnet for Matlab- Lasso (L1) and elastic-net regularized generalized linear models)

分数阶滑模工具箱，可用于解决阶次比较低的时候(fractional order sliding mode )

fortran四阶龙格库塔法 计算程序自己编程(fortran fourth-order Runge-Kutta method)

递归神经网络-实时学习训练算法代码，亲测可用，简洁无误，容易上手。( Recursive neural network- real-time learning training algorithm code, pro-test available, simple and correct, easy to use.)

分别采用Roe格式和AUSM格式求解一维黎曼问题，并将计算结果与解析解进行比较，发现这两种计算格式都能获得高的计算精度。(Roe scheme were used in this procedure and AUSM format to solve a 1-D RIEMANN problem, and numerical results were compared with the analytical solution, the results can be seen from these two formats have a solution with high accuracy.)

本程序用于生成高质量的网格，可用于有限元，有限体积等方法的前处理。(This procedure is used to generate high-quality mesh, can be used for finite element, finite volume methods such as pre-processing.)
