8PSK

Computes the circulant matrix of a vector.

压缩感知的一个经典算法，即SL0算法，在MATLAB7.0下已实现 (A classic compressed sensing algorithm, SL0 algorithm has been achieved under the MATLAB7.0)

面阵中二维角度估计 Unitary -ESPRIT算法MATLAB程序(Two-dimensional planar array of point estimates Unitary-ESPRIT algorithm MATLAB program)

对一个给定的状态转移矩阵求其联合分布矩阵，联合熵，平均互信息量以及共熵。可以画出平均互信息量的曲线(For a given state transition matrix of their joint distribution matrix, the joint entropy, mutual information and the average total entropy. Can draw the curve of the average mutual information)

计算关联维数，利用三线法拟合求斜率，可以画出关联维数随参数变化的曲线(Calculate the correlation dimension, use the three-line method to fit the slope, you can draw the correlation dimension with the parameters of the curve)

读入图像到命令窗口然后按CTRL + ENTER键，执行每一个单元。增强或降低图像亮度，不是普通的灰度调制。(first read any two image in command window then press ctrl+enter to execute each cell .highlight duller value nd increase or decrease the value from cell box to increase or decrease the image)

说明：  冈萨雷斯数字图像处理的一个review 简洁不错(a review of digital image processing)

function [x,n] = stepseq(n0,n1,n2)

弱信号检测中，LFM信号经过匹配滤波器的应用(Weak signal detection of LFM signal in the application of matched filter )

判断两幅图是否一样（包括相似图像的判断和完全不一样的图像判断）(Determine whether the two images the same (including judgments and similar images of a completely different image to check))
