This code realize the root_music algorithm

cfft256程序，很好用的，通信必备的matlab程序(cfft256 procedures, the good, the necessary communication procedures Matlab)

这是介绍基于蚁群优化算法的碎纸拼接的文章(This is to introduce ant colony optimization algorithm shredding stitching articles)

hierarchical clustering in matlab

基于空域平滑滤波的消燥处理程序，该程序可通过界面显示方法进行不同噪声条件下的中值滤波、均值滤波、自适应滤波等方面的消除噪声实验。( the consumption smoothing dry processing based on Airspace)

说明：  该code读出naca4412.txt中基本balde坐标，在读取data1.txt中设计要求，生成FinalCoordinates.txt文件，包含所有生成balde airfoil所需coordinates。(this matlab code read the blade coordinates in naca4412.txt, and then read the design requirements in data1.txt. Finally, it will generate the FinlCoordinates.txt which include all the coordinates of blade airfoil.)

RLS identification algorithm. RLS is used to identify a discrete time model of a plant operating in open-loop based on the recursive least squares method and the UD factorization for updating the adaption gain matrix (F).

二维电源-地同步噪声电磁仿真程序，用FDTD编写的，可以参考一下(applies finite difference time domain method to analyze transmission coefficient.)

使用MATLAB软件将三维图转化为二维图形实现。(Using the MATLAB software to three-dimensional images into two-dimensional graphics to achieve.)

说明：  设计产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，使用矩形窗设计不同特性的数字滤波器对信号进行滤波处理，分析所设计滤波器(画出了频率特性曲线)，并对信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，同时设计出了一个友好的人机交互界面。(Designed to produce a continuous signal, including low frequency, medium frequency, high frequency components, its sampling, spectral analysis, using rectangular windows of different characteristics of digital filter design the signal filtering, analysis of the designed filter (to draw the frequency characteristic curve), and signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, the mean time, a friendly interactive interface.)
