一列火车要将n节车厢分别送往n个车站车站按1~n的次序编号，火车按照n, n-1,…, 1的编号次序经过车站。假设车厢的编号就是其目的地车站的编号。 (A train to n cars n stations were sent to stations by 1 ~ n the order of numbers, the train in accordance with n, n-1, ..., 1 after the station number sequence. Suppose car number is its destination station number.)

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).)

需要一个放有若干图片的文件夹，图片的文件名还需要提供一些信息，如“计61班.jpg”之类，具体格式可以修改源代码。然后显示图片让参与者猜是哪个班的。为系里男生节编写的一个简单的GUI程序(Need a put several pictures folder, pictures of the file name also need to provide some information, such as "(61 class. JPG," and so on, and the specific format can make changes to the source code. And then display picture participants had to guess which class is. For the day of a boy to write simple GUI program)
