merge_sort 利用递归的方法进行归并排序 逆序数

MSP430F449与ATT7022开发的一款三相表demo，完善中，其中的几个程序模块，仅供参考。(MSP430F449 with the ATT7022 the development of a three-phase table demo, perfect, where several program modules for reference purposes only.)

牛顿法， 快速解耦法， 。潮流计算在数学上属于多元非线性方程组的求 解问题，在用迭代法求解时涉及到大量的矢量和矩阵运算，因而寻求一个能高效 地处理矩阵运算的语言，将给潮流计算程序的编制带来巨大的方便.(fast flow electric Power flow calculation is mathematically the solution of multivariate nonlinear equations. Solving the problem involves a large number of vector and matrix operations when solving the iterative method, thus seeking a highly efficient solution. The language of matrix operation will bring great convenience to the compilation of power flow calculation program.)

C# 仿QQ管家UI以及功能源码，效果不错，值得收藏

#ifndef _VPTREE_HEADER_ #define _VPTREE_HEADER_ #include #include #include #include #include #include template class VpTree { public:     VpTree() : _root(0) {}     ~VpTree() {         delete _root;     }     void create( const std::vector& items ) {         delete _root;         _items = items;         _root = buildFromPoints(0, items.size());     }     void search( const T& target, int k, std::vector* results, std::vector* distances) 

摄像头标定的代码,OpenCV没有提供完整的示例，自己整理了一下，贴出来记录。利用cvFindChessboardCorners找到棋盘在摄像头中的2D位置， 再用cvCalibrateCamera2计算内参(Camera calibration code, OpenCV does not provide a complete example of his order a bit, posted record. Use cvFindChessboardCorners find board in the camera' s 2D position, then calculate the internal reference cvCalibrateCamera2)

包含了OpenCV2.4.3的使用手册和函数参考手册，非常适合编程时参考。(Contains a user manual and OpenCV2.4.3 function reference manual, very suitable for programming reference.)
