说明：  实现了DCT的算法，用Matlab实现了任意维图像的DCT变换问题。(DCT algorithm implemented using Matlab implementation of arbitrary-dimensional DCT-image problems.)

to detect the energy in cognitive radio

本程序实现了哈夫曼编码，可以应用在图像处理中压缩图像，属于无损压缩！(huffman)

用matlab软件开发的多个关于梁的例程(Matlab software development with a number of routines on the beam)

在Matlab中画一个给定参数的T分布的图像。(plot a figure of a data for T distribution.)

这两个小程序是matlab的.m文件，06为采用二维中值滤波函数medfilt2对受椒盐噪声干扰的图像滤波，07采用matlab中的函数filter2对受噪声干扰的图像进行均值滤波。(these two small procedure is Matlab. M documents, 06 for 2D median filtering function medfilt2 right by the Salt and Pepper image noise filtering, 07 using Matlab filter2 the function of noise interference by the image filtering.)

Skin effect is the tendency of an alternating electric current (AC) to distribute itself within a conductor with the current density being largest near the surface of the conductor, decreasing at greater depths. The electric current flows mainly at the "skin" of the conductor, between the outer surface and a level called the skin depth

this program calculate the electric and magnetic fildes in rectangular waveguide it is also calculate resonance modes by fft.
