this file contains the matlab codes that calculate dipole antenna characteristics in different wavelength.

ARGS is a MATLAB program which demonstrates command line argument retrieval.

一个关于PageRank算法的matlab例程。可以根据surf 算法的邻接矩阵，pagerank搜寻 page rank。使用了幂法求解特征值。(A Matlab example of Google PageRank method.)

I am simply extracting three types of features from the wavelet transform coefficients, these include: energy, variance and waveform length. You can modify and extract any types of features as you need. ** You need the wavelet toolbox to run this code.

matlab写的数字识别程序，功能基本完成Demo1(matlab write digital identification Demo1)

说明：  利用matlab的gui设计的带有输入和输出功能的界面图形，可视性很强，自己独立编写的数据和图形，学习非常值得(Uses the Matlab GUI design to have the input and output function the interface graph, the visibility is very strong, the data and the graph which oneself compiles independently, the study is very worthwhile.)

改程序可以计算海杂波的一阶和二阶散射系数(可以计算海杂波的一阶和二阶散射系数)

used to write data to excel

说明：  一个模拟雷达杂波的程序代码,对开发雷达模拟方面有借鉴作用。(A simulated radar clutter the code, the development of radar simulation serve as a reference.)

对正弦信号进行傅里叶变换，并对比不同的信号长度与采样频率对结果的影响(Fourier transform of the sinusoidal signal and contrast the different length of the signal with the sampling frequency results)
