带免疫功能的粒子群算法，在matlab环境实现。(With immune function of particle swarm optimization, in the matlab environment realize.)

南极三维坐标转换算法,三维平面坐标系到极方位等角坐标系(3d coordinate system transform of antarctic)

OFDM的基础代码，种类很多，运行完美，很好实用，欢迎大家下载验证(OFDM-based code, many different types of works perfect, very good and practical, are welcome to download validation)

以固定电压输出的逆变器的matlab仿真源文件，我初学逆变器仿真的时候做的，对初学者肯定有用(The fixed voltage three-phase output inverter matlab simulation source, beginner when I do , for some students new to the inverter simulation certainly useful)

The function takes three input arguments (function and two initial guesses belonging to the interval). After iterations, it returns the root of the function. The fourth input argument is to change the stopping criteria of the loop.
