Matlab画地球（高质量同等比例下的地球）(This is matlab file to draw earth)

演示龙格库塔方法的绝对稳定区域，从1阶到4阶，且阶数可以调整。另外，区域的左右边界可以计算出来(Absolutely stable region demonstrates Runge-Kutta methods, from an order to the fourth order, and the order can be adjusted. Further, around the boundary region can be calculated)

利用LDA与SVM实现两类之间的分类程序(classification program between the two classes using LDA and SVM)

说明：  通过直接分析声音文件得到最大似然估计法下的混响时间和混响时间的图像，房间空间的参数来自AIR数据库，数据库里面有多种房间形式的参数形式。(Through the direct analysis of sound files, the images of reverberation time and reverberation time under the maximum likelihood estimation method are obtained. The parameters of room space come from air database, which has many kinds of room forms.)
