matlab 代码，利用分步傅里叶方法求解NLSE方程(matlab code, solve the equation NLSE)

本章有三个目的：一是讲述 MATLAB正常运行所必须具备的基础条件；二是简明地介 绍MATLAB及其操作桌面Desktop的基本使用方法；三是全面介绍 MATLAB的帮助系统。 本章的前两节讲述：MATLAB的正确安装方法和 MATLAB 环境的启动。因为指令窗 是MATLAB最重要的操作界面，所以本章用第 1.3 、1.4 两节以最简单通俗的叙述、算例 讲述指令窗的基本操作方法和规则。这部分内容几乎对MATLAB各种版本都适用。第1.5 到第1.8 节专门介绍 MATLAB最常用的另五个交互界面：历史指令窗、当前目录浏览器、 工作空间浏览器、数组编辑器、M 文件编辑器。 鉴于实际应用中，帮助信息和求助技能的 重要性。本章专设第1.9节专门叙述MATLAB的帮助体系和求助方法。 作者建议：不管读者此前是否使用过MATLAB，都不要忽略本章。(This chapter has three purposes: one is about MATLAB normal operation must have the basic conditions 2 it is concisely interface Salt MATLAB and its operation is the basic way of using the Desktop Desktop Three is a comprehensive introduction of MATLAB help system. About the first two sections in this chapter: MATLAB installation method and the MATLAB environment right start. Because the instructions window Is the most important interface of MATLAB, so this chapter with 1.3 and 1.3 two accounts in the most simple and popular, example Basic operation methods and rules about command window. This part of almost all versions of MATLAB. 1.5 To section 1.8 on another five interfaces: the most commonly used MATLAB command window, the current directory browser history, The workspace browser, array editor, M file editor. In view of practical applications, the help information and skills for help Importance. Set up in section 1.9 of this chapter specifically address the MATLAB help syst)

该代码为多频外差四频相移的原理程序，开发环境为MATLAB,可以帮助初学者快速了解外差法的原理。(The code on multiple frequency heterodyne principle of four frequency phase shift process, development environment of MATLAB, can help beginners to quickly understand the heterodyne principle. )

语音信号处理中，利用winner滤波器去除干扰噪声，达到语音增强的效果(Speech signal processing, and use filters to remove interference noise winner, to the effect of speech enhancement)

这个是上海傲谱分析仪器有限公司整个火焰光度计系列仪器的介绍(This is to introduce the Shanghai Instrument Co., Ltd. proud of the entire spectrum analysis instrument flame photometer series)

关于龙哥-库塔法的简单编写方程，此法参考数值分析中定步长的方法(About Ge- Kutta method of writing a simple equation, this method refer to the numerical analysis method of fixed step size)

这个是用EM开发的单人乒乓球源码，有需要的可以下来看看哦~~~！(This is developed by EM tennis single source, there is a need can look down Oh ~!)

这是仿真多普勒频移对脉压影响的程序，采用Matlab编写。(this is a program about the effect of the Doppler shift on PC.)
