WSN

modeling induction motor. very easy to use

说明：  dpsk信号的调制与解调 是基于matlab开发环境

用Matlab程序测试一个模数转换器ADC的信噪比SNR和有效位数(use matlab to test SNR of a ADC)

This is a Matlab code for Newton method used in numerical methods to solve linear equations .

用matlab编写得一个小程序，一个会变大变小得地球(Matlab was used to prepare a small procedure, a small Earth will change)

这是用matlab编的代码，实现的功能是可以方便的给定一段信号，画出它的频域的频谱图，对写论文有帮助(This is compiled with the matlab code, function is convenient for a given period of the signal, draw its frequency spectrum chart, to help write the paper)

matlab的在离散方式的图像缩放MATLAB 的名称源自 Matrix Laboratory ，由美国MathWorks公司推出。它是一种科学计算软件，专门以矩阵的形式处理数据。 MATLAB 将高性能的数值计算和可视化集成在一起，构成了一个方便的、界面友好的用户环境，并提供了大量的内置函数。(matlab in discrete forms of image scaling MATLAB name from Matrix Laboratory, launched by the United States MathWorks. It is a scientific computing software, specifically the form of matrix data processing. MATLAB will be high-performance numerical computation and visualization integrated together, constitute a convenient, user-friendly user environment and provide a large number of built-in functions.)

说明：  2008年全国数学建模竞赛用matlab程序(In 2008 by the National Mathematical Contest in Modeling matlab program)

用矩阵的奇异值分解法确定ARMA模型的阶次，估计模型参数(ARMA model to determine the matrix of the singular value decomposition of the order, the estimated model parameters)
