一所大学的电磁场课件，讲述的非常有调理、清晰，对学电磁场的朋友很有帮助，极力推荐，希望大家多多下载(The electromagnetic field of a university courseware, on the very conditioning, clear, electromagnetic field school friends very helpful, highly recommended, hope that a lot of download)

说明：  基于matlab,对图片嵌入水印而不被人感知(Based on matlab, embedded watermark on the image and not be perceived)

基于图像区域生长的方法之一 交互式分割法(Image-based region growing methods: interactive segmentation method)

三次抽样插值的第一类边界条件插值，用于数据处理和科学计算，适合matlab科学计算者参考。(First boundary condition cubic interpolation interpolation sampling, data processing and scientific computing is used for scientific computing matlab reference.)

短时能量与过零率，别人写的，好像是可以用的，大家试试啊(Short-term energy and zero-crossing rate, someone else wrote.maybe it can be used, please try it .)

功能较全面的计算器，除了简单的四则运算之外，还增加了三角函数、幂函数和对数函数，另外还增加了shift功能键，可以用来计算反三角函数。使用方法：使用前将.m和.fig文件放到matlab工作目录下（本人R2013放到bin文件夹下）(More comprehensive calculator function, in addition to simple arithmetic, but also increased the trigonometric, exponential function and logarithmic functions, in addition to increasing the shift function keys can be used to calculate the inverse trigonometric functions. Usage: Before using the m and fig files into the matlab working directory (I R2013 into bin folder))

说明：  该文件可实现杨氏双缝干涉仿真，效果nice(This file can realize the simulation of Young's double slit interference, and the effect is nice)

Algorithm for Generating Random Number with Multi-dimensional Discrete Distribution

自己写的一个计算空间时频分布的程序，魏格纳威尔分布原代码(Wrote a frequency distribution calculating space program, Wigner distribution of the original code Weir)

阵列自适应波束形成，利用SNR准则进行自适应波束形成(The array of adaptive beamforming using SNR criterion)
