符号积分法，有中文注释，大家试试，供参考学习~-Symbolic integration, notes in Chinese, we try, for reference to learn ~

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 g
