permutations_entropy

该matlab代码是一个函数。它接受频域电磁场二维空间分布（用矩阵表示），包括幅度和相位，返回avi文件，显示二维电磁场的动画。(The code is a matlab function. It accepts frequency domain two-dimensional spatial distribution of electromagnetic field (with matrix), including the amplitude and phase, back avi files, the animation shows two-dimensional electromagnetic fields.)

基础程序，便于学习matlab，便于初学者掌握(The basis of procedures, to facilitate learning matlab, easy for beginners to master)

说明：  本程序是基于matlab语言编写的有关图像处理的源代码(This procedure is based on the matlab language of the source code for image processing)

巴特沃斯滤波器设置，自行设置阶数、截止频率等滤波器参数(butter-worth filter)

这个是用来计算Haar-like特征数目的，用MATLAB求的某一个矩形特征的数目(This is used to calculate the number of Haar-like features, with the MATLAB find a certain number of characteristics of a rectangular)

高速跳频，调制样式为DPSK(DPSK/FH)，包括信号的发射接收模型，自己写的代码，仅供参考。(High-speed frequency hopping, modulation pattern for DPSK (DPSK/FH), including the launch of signal reception model, write your own code, for reference purposes only.)
