爬山法提取窗户，源数据是地面激光扫描点云(Hill climbing method to extract the windows, the source data is a ground-based laser scanning point cloud)

说明：  CCNA中文笔记第2章 　DoD模型被认为是OSI参考模型的浓缩品,分为4层,从上到下是1.DoD模型的Process/Application层对应OSI参考模型的最高3层 　　2.DoD模型的Host-to-Host层对应OSI参考模型的Transport层 　　3.DoD模型的Internet层对应OSI参考模型的Network层 　　4.DoD模型的Network Access层对应OSI参考模型的最底2层 (CCNA Chinese Notes Chapter 2 DoD model OSI reference model is considered concentrated products, divided into four layers, from top to bottom is 1.DoD Model Process/Application layer of OSI reference model corresponds to the maximum 3-layer model 2.DoD Host-to-Host layer corresponds to OSI reference model Transport Layer 3.DoD model Internet layer corresponds to OSI reference model Network model Network Access Layer 4.DoD OSI reference model layer corresponds to the bottom layer 2)

说明：  求解庞加莱截面的一个程序，有数据，可以直接运行，适合学习(poincare calculate program)

离散傅立叶变换程序及希尔伯特变换程序，希尔伯特变换对于信号变换有重要意义。该程序通过验证，效果理想。 (Hilbert transfer program)

3D 线性有限元算法， 可计算模型形变和应力分布(3D linear finite element method, calculate deformation and stress distribution model)

二分法的Matlab程序实现。求解非线性方程f(x)=0的问题。而方程f(x)是多项式或超越函数又分为代数方程或超越方程。(Dichotomy Matlab program. Solving nonlinear equations f (x) = 0 problems. The equation f (x) is a polynomial or a transcendental function is divided into algebraic equations or transcendental equation.)
