split-step-Fourier

这是中国数学建模中编程交流上分治算法内容，里面提供了很多分治算法的例子(This is the exchange of mathematical modeling in the programming content on the divide and conquer algorithm, which provides many examples of divide and conquer algorithm)

本书分为三部分。第一部分介绍MATLAB面向对象编程基础知识，包括什么是类，类之间的基本关系，以及MATLAB提供的面向对象编程语言的具体功能；第二部分是面向对象编程的进阶篇，对概念进行归类，方面读者在编程中遇到问题时查询和检索；第三部分把面向对象编程的方法应用到实际问题中，并且从实际问题中抽象出一般的解决方法，即为设计模式。 本书可作为高等院校本科师生、研究生MATLAB课程的辅助读物，也可以作为从事科学计算、程序设计的科研人员的参考书。(This book is divided into three parts. The first part introduces the basic knowledge of object-oriented programming in MATLAB, including what is the class, the basic relationship between classes, and the specific functions of object-oriented programming language provided by MATLAB; the second part is the advanced part of object-oriented programming, which classifies the concepts and queries and retrieves when the readers encounter problems in programming. In the third part, the object-oriented programming method is applied to the actual problems, and the general solution is abstracted from the actual problems, that is, the design pattern. This book can be used as an auxiliary reading material for undergraduate teachers, students and graduate students in MATLAB course, and also as a reference book for scientific researchers engaged in scientific calculation and programming.)
