说明：  该程序用matlab编写的，采用crosstrain方法进行模式识别的方法。(the procedures used in the preparation of Matlab, crosstrain using the method of pattern recognition methods.)

说明：  摄像机标定算法的MATLAB语言实现，通过MATLAB实现对摄像机的标定(Camera calibration algorithm of the MATLAB language, through the MATLAB camera calibration to achieve)

常用指令工作空间管理管理指令和函数搜索路径的管理(指令窗控制 运算符和特殊算符(Management of common commands workspace management management instructions and functions of the search path (command window control operators and special operators)

说明：  Write a program in MATLAB for edge detection

function Px=overlay(N,omega,A,sigma,num) OVERLAY Forms multiple power spectral density estimates. ------- USAGE Px=overlay(N,omega,A,sigma,num) Calculates the periodogram using an ensemble of realizations of a process consisting of a sum of complex exponential in white noise. N : length of the signal omega : vector containing the sinusoid frequencies A : vector containing the sinusoid frequencies sigma : the variance of the white noise num : size of the ensemble (number of periodograms)

该程序利用空时二维自适应原理仿真了杂波的二维方向图，计算了杂波协方差矩阵，并画出了二维杂波谱。(The program uses the principle of space-time adaptive simulation of a two-dimensional patterns of the clutter, clutter covariance matrix is ​ ​ calculated, and plotted the two-dimensional clutter spectrum.)

programme in matlab - aproximation 1D & 2D- using square root method
