4种启发式算法的问题的matlab程序，非常的实用(4 kinds of heuristic algorithm of the matlab program, very practical)

以单相光伏发电并网系统为研究对象，针对光伏发电并网技术，深入分析了光伏发电最大功率点跟踪技术和逆变器并网控制技术。在Simulink中搭建了光伏电池模型、基于扰动观测法的MPPT模型和使用电压电流双闭环SPWM控制策略来并网。(Taking the single-phase photovoltaic power grid system as the research object, aiming at the photovoltaic power grid technology, this paper analyzes the maximum power point tracking technology and inverter grid control technology. In Simulink, photovoltaic cell model, MPPT model based on disturbance observation method and voltage current double closed-loop SPWM control strategy are built.)

说明：  最短路径的通用程序，matlab，在网上整理的，有些问题，需要进一步调整。(The shortest path of the general program, matlab, online finishing, some issues require further adjustment.)

本文为基于D-S证据理论的配电网故障选线，使用matlab仿真，结果可信(D-S theory based fault line detection,the simulation is proved right)

a combined solution for all power system related programs in matlab

冈萨雷斯数字信号处理书中部分matlab源码，和示例(image encoding)

本程序是经典的无线传感器网络的Leach协议。(The programe is classic la location algrithom.)

函数通过输入信号序列和函数序号，以及调制解调选择参数来完成扩频调制解调。original_seq是原始输入序列，可能是未调制序列，也可能是调制序列，walsh_num是walsh函数的序号，select选择对输入的序列进行调制还是解调。(function through the input signal sequence and function of the serial number and choice of modulation and demodulation parameters to complete spread spectrum modulation and demodulation. Original_seq is the original input sequence may not be modulated sequence, and may also be modulated sequence, walsh_num walsh function of the serial number, select choice of input sequence modulation or demodulation.)

说明：  用于LFM的分析与生成，可用于仿真雷达信号等(For analysing LFM,it can be used in radar signal and some places.)
