PROBLEMS1. Translate the following paragraphs into Chinese.1.1 The MATLAB desktop appears when the program is started. It integrates many of the MATLAB tools in a single location. These tools include the Command Window, the Command History Window, the Start Button, the Workspace Browser, the Array Editor, and the Current Directory Viewer. The Command Window is the most important of the windows. It is the one in which all commands are typed and results are displayed. 2. Answer the following questions 2.1 List the different ways that you get help in MATLAB. 2.2 Explain the usages of the following tools managed in the matlab desktop,(1) Command Window: (2) Command History:(3) Current Directory Browser:(4) Workspace Browser: (5) Editor/Debugger: . SOLUTIONS1. Translate the following paragraphs into Chinese.1.1 MATLAB启动后会显示其应用界面。该界面集成了MATLAB工具。包括命令窗口，历史命令窗口，开始按钮，工作空间浏览器，数组编辑器以及当前路径查看器。命令窗口时最重要的窗口，在该窗口中可以键入命令与显示结果。2. Answer the following questions 2.1 (1) The preferred method is to use the Help Browser;(2) The second way is to type help or help followed by a function name in the Command Window.(3) The third way to get help is the lookfor command2.2 (1) Run MATLAB functions.(2) View a log of the functions you entered in the Command Window, copy them, and execute them. (3) View MATLAB files and related files, perform file operations such as open, and find content.(4) View and make changes to the contents of the workspace.(5) Create, edit, and debug M-files (files containing MATLAB functions).Chapter 2 Basic MATLAB Commands. PROBLEMS 1. Translate the following paragraphs into Chinese.1.1 The MATLAB language includes an extremely large number of built-in functions to help us solve problems. This list of functions is much richer than the list of functions found in other languages such as Fortran or C+, and it includes device-independent plotting capabilities. A complete list of all MATLAB functions is available through MATLAB HELP, which can be accessed by clicking the HELP icon, or by typing helpdesk in the Command Window. 1.2 The fundamental unit of data in any MATLAB program is the array. An array is a collection of data values organized into rows and columns, and known by a single name. Individual data values within an array are accessed by including the name of the array followed by subscripts in parentheses that identify the row and column of the particular value. (ch2)2.
