X射线检测中黑度与透照参数分布曲线的最小二乘拟合(X-ray inspection of the least-squares fit blackness and Radiographic parameters distribution curve)

说明：  求积分方程的离散解并比较它与真解之间的误差，用n=4的复化Simpson公式求积分方程(Seek solutions of integral equations of the discrete solution and compare it with the error between the real, the complex with n = 4 integral equation of the Formula Simpson)

PCA算法。PCA的目的是找到能够分离出最大方差的方向，所以首先求原来所有数据三个维度上的协方差，然后求这个协方差的特征值，最大特征值为第一个方向，从此以此类推。(PCA algorithm. The purpose of PCA is to find able to isolate the direction of maximum variance, so first find all the data in three dimensions on the original covariance, and then find the eigenvalues ​ ​ of the covariance, the biggest feature is the first in one direction, from and so on.)

雷达信号处理中，利用ECA_B算法，实现直达波及多径的抑制(In radar signal processing, the ECA_B algorithm is utilized to realize the suppression of the direct spread and multipath.)

一些matlab的程序，如交互多模，CA,CV,Singer模型的一些仿真仅供参考。(Some matlab procedures, such as interactive multimode, CA,CV,Singer model of some simulation is for reference only.)

说明：  信号处理工具箱,用MATLAB来进行信号处理(Signal Processing Toolbox with MATLAB for Signal Processing)

说明：  直接型自适应滤波器的源码，并能实时跟踪测量信号频率，滤除白噪声和谐波(Direct source-type adaptive filter, and real-time tracking and measuring the signal frequency, filtered white noise and harmonic)

说明：  循环平稳时间序列中关于高阶循环累积量的程序 (Cyclostationary time-series on high-order cumulant of the process cycle)

说明：  基于matlab的K均值聚类程序。其中用IRIS数据进行验证，得到了很好的结果。文件中包含了演示后的结果图(Matlab-based K-means clustering procedure. Which use IRIS data verification, have had good results. File contains the results of the demonstration plan)

这是一个vblast程序，天线数可以根据要求设定，接受端的检测采用mmse－pic的方式(vblast This is a process, several antennas can be set according to demand, receivers used to detect the mmse-pic approach)
