BESO的python程序，对于进行abaqus的二次开发很有帮助，这样可以将有限元单独在abaqus中进行处理，而优化算法则采用python进行编写(BESO python program, for the secondary development abaqus helpful, so that the finite element can be handled separately in abaqus, while the optimization algorithm is written in python)

matlab中实现箭头的程序，直接作为函数使用。(matlab realize the arrow in the procedure)

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)

一个案例代码，用最小二乘支持向量机的，预测煤炭量(A case code, using the least squares support vector machine to predict the volume of coal)

解线性代数方程组的顺序高斯消去法。使用c++标准库的vector实现。(Solution of linear algebraic equations order Gaussian elimination. Use c++ standard library vector implementation.)

说明：  二级转运站选址数学规划模型求解的lingo 程序(Lingo Program for Solving Mathematical Programming Model of Secondary Transfer Station Location)

说明：  在matlab环境下能进行各种曲线拟合的算法，非常好。(In the matlab environment to conduct various kinds of curve fitting algorithms, very good.)

地球固连坐标系与地球惯性坐标系的转换矩阵程序，考虑的章动、岁差、自转等。(Earth' s solid even coordinate system with the Earth inertial coordinate system transformation matrix program, consider the nutation, precession, rotation, etc..)

说明：  贝叶斯统计推断相关资料和贝叶斯方法，学习贝叶斯不错的资料(Bayesian statistical inference related data and bayesian methods, learning bayesian good data)

对于方程组AX=b，当系数矩阵非奇异时，对原方程进行改写，利用公式X^k=BX^(k+1)+g进行迭代求解。(For equations AX = b, when the coefficient matrix is ​ ​ nonsingular, rewriting the original equation, using the formula X ^ k = BX ^ (k+1)+g for iterative solution.)
