distance vector based range free localization

PID+genetic algoritm

说明：  AR谱估计函数，内置基于FPE准则、AIC准则以及CAT准则判定AR阶数(AR spectral estimation function, built-in standards-based FPE, AIC criteria and guidelines to determine the AR order of CAT)

根据已知的三维离散数据（x,y,z）,在MATLAB中利用此函数进行三维曲面拟合，再根据polyval2d得出拟合函数的系数矩阵。(according to 3D discrete datum (x,y,z),use this function in MATLAB to fit 3D surface, and use polyval2d to get coefficient matrix)

说明：  matlab潮流计算程序 多是基于输电网开发的，而对于配电网中的潮流计算程序较少，真对辐射型配电网的特点，开发了用于配电网潮流计算的MATLAB程序，该程序采用新的支路选择方法，无需对网络进行复杂的编号。(matlab flow calculation procedure is based on multi-grid development, and for power distribution network power flow calculation program less true on the characteristics of radial distribution networks, developed for distribution power flow calculation of the MATLAB program that uses the new branch selection method, without the complexity of the network number.)

用于计算盒维数的程序，分形维数的一种,分形理论是近年热门(it is for capacity dimension, and the capacity dimension is one of the fractal dimensions。Fractal thoery is the heat tropic nowadays)

用MATLAB实现自适应神经模糊推理系统（ANFIS）结构训练。代码中，首先创建一个初始原ANFIS结构，然后采用遗传算法（GA）、粒子群优化（PSO）来训练ANFIS。此进化训练算法可用于解决非线性回归函数逼近问题。(Implementation of adaptive neural fuzzy inference system (ANFIS) based on MATLAB. Code, the first to create an initial original ANFIS structure, and then using the genetic algorithm (GA), particle swarm optimization (PSO) to train ANFIS. This evolutionary training algorithm can be used to solve the nonlinear regression function approximation problem.)
