抛物线拟合算法实现代码，已经通过测试可指直接运行(Parabola fitting algorithm code, has passed the tests can be run directly refers to)

非常好的matlab代码，欢迎下载分享学习！！！(this is a very good！！！！！！！！！)

说明：  matlab编程的好工具 toolbar(toolbar welcome)

matlab中add path代码，初学者，大家互通有无(for matlab)

In short, to-the-point chapters, Practical C++ Programming covers all aspects of programming including style, software engineering, programming design, object-oriented design, and debugging. It also covers common mistakes and how to find (and avoid) them. End of chapter exercises help you ensure you ve mastered the material. Steve Oualline s clear, easy-going writing style and hands-on approach to learning make Practical C++ Programming a nearly painless way to master this complex but powerful programming language.
