新的彩票预测抄来的！真的是抄来的！真的真的真真的！(The new lottery prediction copy to Really copied! Really, really Barbara!)

abaqus Umat 计算复合材料的损伤问题，可以学习一下(abaqus umat subroutine for damage of the composite material)

Mathematica计算基于力平衡变截面梁单元的质量和刚度矩阵(2D force-based finite element mathemaica)

针对多期随机规划问题，利用情景树方法来求解(For multi-period stochastic programming problems, the use of scenarios to solve Tree)

内点惩罚函数法C语言程序，适用于机械行业机械优化设计(SUMT)

说明：  这是数值分析的一些作业实验，文件中有详细的文档对理论，实验和算法的说明，用于病态方程组求解的源代码(This is the numerical analysis of the experimental operation, the paper detailed documentation of theory, experiment and the algorithm shows that morbid equation for solving the source code)

利用风速u,v计算海表风应力以及风应力旋度。(Calculation of sea surface wind stress and wind stress curl.)

LU decomposition program.

说明：  一般的最小二乘通常是一次拿到全部的数据， 对所有数据进行统一优化计算得到模型系数。递推最小二乘是以一种递推的方式计算最小二乘，每次使用最新的测量值，来不断更新模型系数。(General least squares usually get all the data at one time, and perform unified optimization calculations on all the data to get the model coefficients. Recursive least squares is to calculate the least squares in a recursive way, each time the latest measured value is used to continuously update the model coefficients.)

本程序应用python编程，用到3机9节点算例，数据也给出，可以实现潮流计算。(This program uses python programming, uses 3 machines and 9 nodes to calculate the example, and the data is also given, which can realize the load flow calculation.)
