K-d树实现。采用matalb和C++混合编译的方式实现。(kdtree provides a minimalistic implementation of kd-tree. The implementation can be used either inside MATLAB by means of MEX calls, or as a standalone tool, directly a C/C++ program. )

模拟退火算法简介及解决实际问题的代码Matlab程序(Introduction and simulated annealing algorithm to solve practical problems Matlab program code)

GPS输出的经纬度坐标转换为大地直角坐标(GPS output of geodetic latitude and longitude coordinates is converted to Cartesian coordinates)

利用双缓冲技术实现使得能用鼠标在桌面上轻松画取圆形，(The use of double-buffering technology makes the mouse can be used to easily draw on the desktop to take round,)

作为算法实现的应用,对光子晶体光波导的电磁耦合效应进行了数值仿真研究,结果证实:波导耦合区域内不同半径比介质柱所导致的结构变化将造成耦合长度的改变,且其耦合关系曲线具有平稳区与迅变区两类不同特性的变化范围区间。(As the algorithm' s application, on the photonic crystal waveguide for electromagnetic coupling numerical simulation, results show: waveguide coupling region different than the dielectric cylinder radius of the structural changes caused by the coupling length will cause a change, and its coupling curve has a smooth area with the fast-changing area characteristics of two different range interval.)
