Description: 在最优控制、变分法、微分方程等学科中常遇到两点边值问题( TPBVP ),徒手求取解析
解比较繁；MATLAB 的符号数学工具箱却又仅限于解一点边值问题。本示例阐述如何用符
号数学工具箱解 TPBVP。-In optimal control,variational calculus and differential equation frequently encountered two-point boundary value problems(TPBVP).Free-hand to get a analytical solution is difficult a bit,but symbolic math toolbox only solved one-point boundary value problem. How to use this toolbox to get the analytical solution of TPBVP are illustrated by examples.

Description: 使用MATLAB解微分方程，包括初值问题，边值问题，时延问题-This book is for people who need to solve ordinary differential equations (ODEs), both initial
value problems (IVPs) and boundary value problems (BVPs) as well as delay differential
equations (DDEs). These topics are usually taught in separate courses of length one semester
each, but Solving ODEs with MATLAB provides a sound treatment of all three in about 250
pages. The chapters on each of these topics begin with a discussion of “the facts of life” for
the problem, mainly by means of examples. Numerical methods for the problem are then developed
– but only the methods most widely used. Although the treatment of each method is
brief and technical issues are minimized, the issues important in practice and for understanding
the codes are discussed. Often solving a real problem is much more than just learning how
to call a code. The last part of each chapter is a tutorial that shows how to solve problems by
means of small but realistic examples.

Description: 1. 在matlab中分析基于分离变量法的解析解；
2. 利用简单迭代法求解，与解析法结论对比，分析求解结果的精确度。分析过程至少包括：在网格尺寸为0.1 m和1 m两种条件下，两次迭代差值最大为10-10时的分析结论；
3. 利用超松弛迭代法分析，选择松弛因子，分析其对收敛速度（即迭代次数）的影响，并确定最优值。分析过程至少包括：在网格尺寸为0.1和1两种条件下，两次迭代差值最大为10-10时，迭代次数随松弛因子的变化，得到对应的最优松弛因子，与经验值（课本165页式子3.7.15）进行对比。(1. Analyze the analytical solution based on the separation variable method in matlab.
2. Using a simple iterative method to solve, compared with the results of the analytical method to analyze the accuracy of the solution. The analysis process at least includes the following conclusions: when the mesh size is 0.1m and 1m, the maximum difference between two iterations is 10-10.
3. Analyze using the relaxation relaxation iteration method, select the relaxation factor, analyze its influence on the convergence speed (ie the number of iterations), and determine the optimal value. The analysis process at least includes the following: when the mesh size is 0.1 and 1 and the maximum difference between two iterations is 10-10, the number of iterations varies with the relaxation factor, and the corresponding optimal relaxation factor and empirical value are obtained ( Textbook 165 pages (3.7.15) for comparison.)

Description: matlab提供了边值问题求解器bvp4c（）用于求解边值问题的数值解，bvp4c（）采用带自适应网格的高阶差分法来求解边值问题，首先给出可调用的常微分方程组函数以及残差的边值条件函数，这些函数都必须返回一个列向量。(Matlab provides the numerical solution of the boundary value problem solver bvp4c () for solving the boundary value problem. Bvp4c () uses the high order difference method with adaptive grid to solve the boundary value problem. First, we give the invocable ordinary differential equation set function and the residual boundary value condition function. These functions must return a column vector.)
