软件简介Software Introduction
MATLAB是matrix&laboratory2个词的组成，意为引流矩阵加工厂（引流矩阵试验室），软件关键应对计算机的应用、数据可视化及其互动式编程设计的新科技云计算平台。它将数值计算方法、矩阵运算、科学合理大数据可视化及其线性信息系统软件的模型和模拟仿真等众多强劲作用集成化在一个容易应用的窗口自然环境中，为科研、建筑工程设计及其务必实现合理数值计算方法的诸多科学领域给予了一种全方位的解决方法，并在较大水平上解决了传统式非互动式程序语言（如C、Fortran）的编写方式
MATLAB is a combination of the two words matrix&laboratory, which means matrix factory (matrix laboratory). The software mainly faces the high-tech computing environment of scientific computing, visualization and interactive programming. It integrates many powerful functions such as numerical analysis, matrix calculation, scientific data visualization, and nonlinear dynamic system modeling and simulation in an easy-to-use window environment. It is used for scientific research, engineering design, and many sciences that must carry out effective numerical calculations. The field provides a comprehensive solution, and to a large extent get rid of the editing mode of traditional non-interactive programming languages (such as C, Fortran).
Matlab特点Matlab features
- 语言表达简约、灵便（关键编码关键运用C语言来完成）language introduction, flexibility (the core code is mainly implemented in C language)
- 丰富多彩的操作符Rich operators
- 可玩性高High degree of freedom
- 强劲的图像作用（二维三维乃至四维图型的绘图和解决）Powerful graphics functions (drawing and processing of two-dimensional, three-dimensional and even four-dimensional graphics)
- 丰富多彩的辅助工具Rich toolbox
- 源代码的开放式The openness of the source program
- 优良的软件插口（可以与maple、excel、word软件开展通信互动）Good software interface (can communicate and interact with maple, excel, word software)
Matlab9.0
关键对话框详细介绍Main window introduction
- 脚本制作对话框：大批量编写要运作的编码
- 命令窗口：键入指令，在其中标记“》”表明matlab早已准备好运行命令
- 工作区域（工作流程管理对话框）：存储被理解的自变量
- 当前目录对话框（工作中途径）：表明现阶段存储指令的详细地址
- 菜单栏（工具栏）：如下图所示
① Script window: batch edit the code to be run.
② Commind window: input the command, the symbol “”” means that matlab is ready to execute the command.
③ work area (work management window) work space: store the defined variables.
④ Current directory window (working path) current directory: display the address of the current storage command.
⑤ Toolbar (menu bar): as shown in the figure.
Matlab好用提议Matlab practical suggestions
1.工作中途径的挑选The choice of working path
- 编写前留意各项工作的文件夹名称，客户可以挑选变更途径Pay attention to the current working folder before editing, the user can choose to change the path.
- 当脚本文件的路径与各项工作途径不一致时，点一下运作脚本制作指令，系统软件会提醒如下所示When the path of the script file is inconsistent with the current working path, click the run script command, the system will prompt as follows:
2.应用脚本制作编写编码Use the script to edit the code
优势；便捷查询、改动、存储和逐一运作
Advantages：easy to view, modify, store and run one by one
3.适度清除工作区域Properly clean up the work area
- 方式一：命令窗口键入clear后按住enter键
- Method 1: Enter clear in the command window and press enter.
- 方式二；点一下工作区域的往下的小箭头挑选“清除工作区域”
- Method 2: Click the small downward arrow in the work area to select “Clear Work Area”.
4.搜索历史时间指令Find historical commands
- 在应用全过程中，假如键入指令不正确可以回到上一条或以前的指令，再次编写In the process of using, if the input command is wrong, you can return to the previous or previous command and re-edit.
- 方式一（适用指令少的状况）：进到命令窗口-鼠标光标驻留在全新一条指令处-立即按住电脑的up键
- Method one (applicable to the situation with few commands): Enter the command window-the cursor stays at the latest command-directly press the up key on the computer.
- 方式二（指令较多或是较复杂）：开启历史时间命令窗口-双击鼠标指令就可以运作
- Method two (more commands or more complicated): open the historical command window-double-click the command to run.
5.Help的调用Help call
在应用matlab时，假如想查阅matlab的有关知识要点，可以调用help，具体做法如下所示：在命令窗口立即键入help-挑选相对应的主题点一下查阅就可以When using matlab, if you want to consult the relevant knowledge points of matlab, you can call help, the specific method is as follows: directly enter help in the command window-select the corresponding topic and click to view.
