Quarter

主要用于三次样条拟合，对离散点进行拟合插值，(Three order spline fitting)

程序采用C语言，实现最小二乘辨识算法和递推最小二乘算法(Program using C language, least squares identification algorithm and recursive least squares algorithm)

对简单开式网前推回代法计算潮流方便，已通过编译，有运行结果(back forward power flow)

给出一个求解连续混沌系统的最大Lyapunov指数的程序，经验证有很好的吻和度，并能应用的高维（超混沌）或其他混沌系统。(Solving a continuous chaotic system is given the maximum Lyapunov index procedure, proven good kiss and degrees, and can use the high-dimensional (super-chaotic), or other chaotic systems.)

LU decomposition program.

ansys-初应力-残余应力-焊接残余应力-ansys温度场(ansys-initial stress)

多物理场耦合软件采用有限元方法模拟表面等离子体激元，适合入门学习者(Multi-physics coupling software using the finite element method to simulate the surface plasmon, suitable for entry-learners)

利用AR模型进行时间序列预测的程序源代码，使用最小二乘估计法进行参数估计。拟合效果非常好。(use AR model for time series prediction of the source code, the use of least squares estimation method to estimate parameters. Fitting very good results.)

三相潮流计算，使用的是牛顿拉弗逊方法。迭代较快。是解决潮流的较有效的方法。(Three-phase power flow calculation, using Newton' s method Laffer Johnson. Iterate rapidly. The trend is to solve the more effective method.)

通过matlab计算allan variance，较为复杂，注释详细(Matlab Allan variance, more complex, detailed notes)
