阵列对接收的宽带噪声调频信号采用极大似然法测向(For wideband noise frequency modulation signal received by the array,using the maximum likelihood method to estimate the AOA)

说明：  VMD是通过迭代搜寻变分模型（具体怎么搜寻，请亲们自己看，我主要讲他的大概）最优解， 来确定我们所知的模态uk(t)及其对应的中心频率ωk和带宽。 每个模态都是具有中心频率的有限带宽（就是在频域中有在一定的宽度）。所有模态之和为源信号。(VMD is to determine the modal UK (t) and its corresponding central frequency, k and bandwidth by iteratively searching for the optimal solution of the variational model (see dear friends for details, and I will mainly talk about his approximate solution). Each mode is a finite bandwidth with a central frequency (that is, a certain width in the frequency domain).The sum of all modes is the source signal.)

0-1整数规划问题，采用MATLAB编程，约束条件等可以改变，比较实用(0-1 integer programming problem, the use of MATLAB programming, constraint conditions can change, more practical)

Use shading to represent secondary information of an image(Use shading to represent secondary inform ation of an image)

此为模式识别中的Fisher线性判别方法求分类器。进行了男、女错误率和总错误率的统计。 全部程序流程如下： 1、读取FAMALE.TXT文件把身高或体重给数组，并求x1的样本均值m1和内离散度S1； 2、读取MALE.TXT文件把身高或体重给数组，并求x2的样本均值m2和内离散度S2； 3、求最佳变换向量和阀值点； 4、读取Test2.txt文件把对应的身高或体重给数组A并求A的样本数M； 5、把最佳变换向量和阀值点、x代入判别方程g（x）； 6、对本判别的错误率进行统计。(This is the pattern recognition method, to calculate the Fisher linear discriminant classifier .Were male , female and total error rate error rate statistics . All program flow is as follows : 1 , read FAMALE.TXT file to height or weight to the array, and find the sample mean m1 x1 and internal dispersion S1 2 , read MALE.TXT file to height or weight to the array, and find the sample mean m2 and x2 within the dispersion S2 3 , for the best transformation vector and the threshold point 4 , read Test2.txt file to the corresponding height or weight requirements for the array A and A is the number of samples M 5 , the best transformation vector and the threshold point , x substituted into the discriminant equation g (x) 6 , determine the error rate of the statistics . )

说明：  Harris corner detection function

自编奇异值MATLAB程序，利用奇异值去除信号噪声。以供参考。(Editing the singular value MATLAB, using the singular value to remove noise signal. For your reference.)

一维灰度矩，用matlab进行编程，输入为一维灰度序列，输出为边缘值。不能直接处理图像！但有学习研究价值。(One-dimensional gray moment, using matlab programming for one-dimensional gray-scale input sequence, the output value for the edge. Can not directly deal with the image! But learning research value.)
