点云曲面建模，基于距离函数，运用移动最小二乘法，拟合曲面，提取等值面，用于散乱点云的快速三角网格构建(Point cloud surface modeling, based on the distance function, the use of moving least squares method, fitting surface, isosurface extraction for fast scattered point cloud build triangular mesh)

ANSYS二次开发考虑损伤的材料模型子程序(ANSYS subroutine)

ADAM （Adaptive Moment Estimation）是另外一种自适应学习率算法，它结合动量梯度 下降法，在不同参数方向上采用不同学习率，保留前几次迭代的梯度，能够很好 的适应于稀疏数据。(ADAM (Adaptive Moment Estimation) is another adaptive learning rate algorithm, which combines momentum gradient. The descent method, which uses different learning rates in different parameter directions and retains the gradients of previous iterations, is very good. It is suitable for sparse data.)

FDTD中利用监视器电场提取S11，S21，S12，S22参数(In FDTD, S11, S21, S12, S22 parameters are extracted from the monitor electric field.)

简单地实现了一、二、三维的K均值聚类，效果还不错，适合初步学习模式识别的同志们(Simple implementation of one, two, three - dimensional k-means clustering, the effect is not bad, it is suitable for the initial learning pattern recognition comrades)

用Roe格式的一阶迎风差分方法解决欧拉方程的黎曼问题(Solves the Riemann problem for the Euler equations using Roe s first-order upwind method )

变增益PID算法的c++实现，目前PID算法较多的是c代码写的，这里上传一个C++的(Variable gain PID algorithm c++ to achieve, the current is more PID algorithm code written in c, where a C++ From the)

说明：  编程观察无穷级数 1/n的收敛性。 采用 IEEE 单精度浮点数，观察当 n 为何值时求和结果不再变化，将它与理论分析的结论进 行比较 (注：在 MATLAB 中可用 single 命令将变量转成单精度浮点数)。(Programming observation of convergence of infinite series 1/n)

说明：  Galerkin method,a numerical approximate method based on weighted residual method,commonly used in differential equation.(Galerkin method,a numerical approximate method based on weighted residual method,commonly used in differential equation.)
