在第一个图像中的每个描述符，选择它的匹配到第二个图像。(For efficiency in MATLAB, calculating dot multiplication between unit vectors is faster than Euclidean distance. Please note that: The ratio of attention to angle (the cosine of dot product of unit vector) is the approximate value of the ratio of Euclidean distance of small angle.)

最小二乘支持向量机做预测。程序可运行学习。在matlab上运行。(This is a program about prediction using LSSVM.It can run successfully for learning.This program can be used on matlab.)

迭代最小二乘法,反演中应用极广泛，非常经典(Iterative least-squares method，An extremely wide range of inversion, very classic)

这是一个求解NACA0012翼型在不同马赫数与攻角下的流场的Fortran源代码。计算格式采用了原始AUSM、AUSMDV以及AUSM+格式。为了提高计算精度，使用了不同限制器的MUSCL插值。(This is a Fortran source code for solving the flow field around the NACA0012 airfoil at different Mach numbers and angles of attack. The scheme of AUSM, AUSMDV and AUSM+ are employed for this code. In order to improve the calculation accuracy, the MUSCL interpolation with various type limiter are used.)

采用 Lax-Wendroff算法计算非粘Bergers方程(nonviscous Burgers equation, Lax-Wendroff method.)
