用费涅尔波带片模拟透镜成像，光波衍射模拟(toll Nieerbei zone plate imaging lens simulation, simulation wave diffraction)

介绍了matlab程序设计方法，并给出了一些具体实例(it introduces matlab program designing method,and it gives some specific examples.)

图论中的最小生成树模型，基于MATLAB实现(The minimum spanning tree graph theory model, based on MATLAB implementation)

说明：  EMD/EEMD的执行的模块,用于对信号进行分解，得到各阶IMF分量(EMD/EEMD the implementation of the module for the signal decomposed IMF components of the order)

信号在多径衰落信道中传输特性的研究 当信号在无线信道传播时，多径发射和衰减的变化将使信号经历随机波动。因此，无线信道的特性是不确定的，随机变化的。(Signal in multipath fading channel transmission characteristics)

精通matlab，经典matlab教材，word版本，有附录(Proficient in matlab, classic matlab materials, word version of the appendix has)

说明：  对于给定的滤波器参数，利用脉冲响应不变性法设计数字低通滤波器，并绘出了设计后的数字滤波器的特性曲线。(This code uses impulse invariant method to design a digital low-pass filter under given filter parameters,then it plots the designed filter s characteristic curve.)

说明：  相控阵天线六边形阵与矩形阵方向图，圆形喇叭天线方向图(Phased array antenna array and hexagonal array pattern of rectangular, circular horn antenna)
