％ [nearest_neighbours] = find_nearest_neighbours( database, desc, max_dist ) ％ Find the indices of the nearest neighbours of the given desriptors in the近邻点寻找算法，在非线性时间序列中很有用，是常用的算法- [Nearest_neighbours] = find_nearest_neighbours (database, desc, max_dist) Find the indices of the nearest neighbours of the given desriptors in the neighbor-point search algorithm, the nonlinear time series of very useful, is a commonly used algorithm

工程问题中常用微分方程的形式建立数学模型，所以微分方程求解很有意义。本程序用Euler、改进Euler和经典公式对这类方程进行求解-Engineering problems commonly used in the form of differential equations to establish the mathematical model, it makes sense for solving differential equations. This procedure used Euler, improved Euler and the classical formula of such equations to solve

应用背景程序求解完全的二维N-S方程，考虑了粘性和导热。当来流Mach数为4时，计算结果与书上的结果一致，然而，我的程序不能计算Mach数为25的情况（即书中提供的另一种工况的比较结果），经过仔细检查，我认为自己的程序没毛病，可能是书中求解步长的公式给错了（eq.(10.16) in p.457），还望大家帮助检查一下。最后还要说明的是，该章在指导你写程序时，书上有些关键地方有印刷错误，会误导你，一定要小心。参考文献：Chapter 10, Computational Fluid Dynamics, The Basics with Applications, John D.
