利用函数MadHG生成规则LDPC码的校验矩阵H，其行重为6,列重为3,行数为列数一半(行数越大越好)，H中任意两列没有围长为4的圈，并得到H对应的生成矩阵G，可以保证mod(G*H ,2)=0。使用方法为:[H,G] = MadHG(m,n,x),x= 1(得到的G左半部分为单位阵) or 2(G右半部分为单位阵),(use function MadHG Generation rules LDPC check matrix H, re-6, series of three, out for a few half of the number (A bigger the better), H 2 arbitrary no girth of the four circles, H counterparts and with the formation of matrix G, we can be assured of mod (G* H, 2) = 0. To be used : [H, G] = MadHG (m, n, x), x = 1 (the G part of the Left Front units) or 2 (G right half of the units RUF),)

采用电导增量法的光伏系统最大功率点跟踪matlab/simulink仿真，可正确运行，可自行修改光照强度和环境温度(Incremental conductance method using the maximum power point tracking photovoltaic systems matlab/simulink simulation can be run correctly, you can modify the light intensity and ambient temperature)

基于RSSI的距离测量 matlab 将接收信号强度RSSI转化为距离，发射信号经衰减到达接收端,根据接收信号的强弱计算T-R距离(RSSI-based distance measuring the received signal strength RSSI matlab converted into distance, attenuated transmitted signal arrive at the receiver end, according to the strength of the received signal the calculation TR)
