Matlab中实现轮对分析的程序以及相关的程序包,可以实现火车轮轨接触关系的分析(Matlab achieving round of analysis of the procedures and the relevant package, can be achieved train wheel-rail contact between the analysis)

以二体问题为模型，从地球发射航天器探索火星，途中需经过一次无动力金星借力，寻找最优（总速度增量最小）的发射时间窗口和飞行时间，并绘制地球到金星的Pork-Chop发射能量等高线图。发射时间窗口为2023—2033年，总飞行时间不得大于2年。(Taking the two body problem as the model to explore Mars from the earth, it is necessary to seek an unpowered Venus transit force on the way to find the optimal time window and time of flight (the minimum total velocity increment), and draw the contour map of the Pork-Chop emission energy of the earth to Venus. The total launch time window is from 2023 to 2033, and the total flight time is not more than 2 years.)

VC++下调用matlab图形库函数进行绘图并显示到VC的图形界面中。(VC call Matlab graphics library functions and mapping indicates that the VC graphics interface.)

本书第一章系统讲述 MATLAB6.5 的集成工作平台，引导读者初会MATLAB 基本用法。 第二、三章系统叙述MATLAB6.1 的四大基本数据类型（数值数组、字符串数组、元胞数组、构架数组），至于其它扩展数据类型（函数句柄、符号数据、内联函数、unit 数组、稀疏类）则另辟章节专述。此后，本书用九个独立章分述MATLAB6.5 的数值计算、符号计算、函数和数据可视、面向对象编程、GUI 交互操作界面设计、EXE 独立应用程序生成、实现不同软件平台交互的API、M-book 数据图形文字环境集成等八大通用功能。本书用专门的一章深入浅出地阐明SIMULINK 的分层建模、仿真功能、MATLAB 交互的功能。(This book first chapter of system narrated that the MATLAB6.5 integration working platform, guides the reader first meeting MATLAB essential usage. Second, third chapter of system narrate the MATLAB6.1 four big basic data type (value array, string of character array, structure cell array, skeleton array), as for other expansion data type (function handle, mark data, internal integration function, the unit array, sparse kind) in addition wards off the chapter to state specially. Hereafter, this book with nine independent Zhang Fenshu MATLAB6.5 numerical calculus, the mark computation, the function and the data visible, the object-oriented programming, GUI operates the contact surface design, the EXE independent application program generation, to realize different software platform interactive API, the M-book data graph writing environment integration alternately and so on eight big general functions. This book expounds the SIMULINK lamination modelling, the simulation function with prof)
