说明：  利用matlab实现电磁场数值方法里面的有限差分与有限元法(Using matlab to achieve numerical method of electromagnetic field inside the finite difference and finite element method)

matlab svm的gui操控界面，绝对可用！！！能够实现分类预测等强大的功能，可以根据自身需求设置各种参数！(GUI control interface matlab SVM, absolutely available!!! To achieve functional classification prediction, powerful, you can set various parameters according to their own needs!)

types of mask useful in image processing

说明：  Matlab中的画圆函数。Matlab本身没有画圆的函数。本附件实现了画圆函数。(Drawcircle function in Matlab. Matlab does not have drawcircle function. Of this Annex drawcircle realize the function.)

50－channel的polyphase filter，基于FIR滤波器(50-channel of the polyphase filter, based on the FIR filter)

new model varying load frequency control

介绍EMD（经验模式分解）的函数基本调用和参数设置(introduce the function using and paramater setting of EMD)

说明：  QPSK完整的调制解调程序，直接在matlab里运行就能得出准确的结果，方便(QPSK modulation and demodulation complete program to run directly in matlab accurate results can be obtained to facilitate)
