这是我从网上下载到的Locally Linear Embedding(LLE)的Matlab代码，希望对研究Manifold Leanring的同事有所帮助(This is I downloaded from the Internet to the Locally Linear Embedding (LLE) of Matlab code, and hope to the study of Manifold Leanring colleagues help )

通过幅相误差存在的情况下MUSIC谱峰与未存在幅相误差时的比较，可以看出幅相误差对DOA估计还是有很大的影响。此程序中加入的幅相误差参数服从高斯分布(Through the case of amplitude and phase errors exist MUSIC peaks when compared with the amplitude and phase error does not exist, it can be seen amplitude and phase errors have a lot of influence on DOA estimates. Amplitude and phase errors of the parameters of this program by adding Gaussian distribution)

说明：  自己编写的计算光流场的MATLAB程序，基于梯度的方法，非常简单(I have written a MATLAB calculation of optical flow procedures, based on the gradient method and it is very simple)

正交最小二乘辨识算法 该算法除了实现最小二乘辨识功能之外而且能按照各项重要性将其逐一选出并且估计相应系数(OLS Orthogonal Least Quares. [x, ind] = OLS(A,b,r) gives the solution to the least squares problem using only the best r regressors chosen from the ones present in matrix A. This function also returns in the vector ind the indexes of the best r regressors (i.e., the best columns of A to use). If r is equal to n, the solution x given by OLS is the same as the solution given by A, but in ind we still have the regressors sorted by their importance. This means that one can perform a feature selection by taking the first k entries in ind (k<r).)

说明：  抛物线法求解 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定. (parabolic equation method Construction Methods : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)

这个程序是vc和simulink的混合编程,在vc中调用simulink,对初学者会有很大的帮助...(This program is a mix of programming of vc and simulink in vc call simulink, there will be a great help for beginners ...)
