matlab benchmarks for otimization problems

一阶导数的常用差分逼近 求解df的差分逼近 flag标记使用的差分算法 算法来自周超红的《一阶导数的差分逼近汇总》 可按照里边的算法构造更高阶的差分逼近(First derivative of the common difference approximation approach for solving differential df flag tag algorithm using the difference method from the week of super-red " first derivative of the difference approximation of summary" can be constructed in accordance with the algorithms inside the differential approximation of higher order)

说明：  数据拟合分析源码，Matlab数理统计与分析上案例分析，希望对您有用(stepwise analy source)

球面网格点判断，找到合适的三角点，不成熟，请见谅。(spherical grid judgment, to find a suitable Triangle, immature, and I do apologize.)

用MATLAB仿真现代谱估计中的周期图算法(Simulation with MATLAB in the periodogram spectral estimation algorithm)

是给一个有限长序列补零（可以在前面或后面补零），用Matlab画图比较原序列，前补零序列以及后补零序列(very good)

Optimization LM method

说明：  运用P-Q分解法进行电力系统潮流计算，本程序用的是IEEE-14标准节点数据。(PQ decomposition method using power flow calculation, this procedure is used in standard IEEE-14 node data.)
