## 统计代写|excel代写代考|A Bird’s-Eye View of Excel

Excel relies primarily on the onscreen element called the Ribbon, which is how you select the vast majority of Excel commands. In addition, Excel offers a single toolbar (the Quick Access toolbar, which is hidden by default), some contextsensitive buttons and command bars in the form of the Quick Analysis tool and mini-bar, contextual tabs that only appear on the Ribbon when you select certain Excel elements (such as a table or image), along with a number of task panes (such as Clipboard, Research, Thesaurus, and Selection to name a few).

Among the features supported when selecting certain style and formatting commands is the Live Preview, which shows you how your actual worksheet data will appear in a particular font, table formatting, and so on before you actually apply it. Excel also supports an honest-to-goodness Page Layout view that displays rulers and margins along with headers and footers for every worksheet. Page Layout view has a zoom slider at the bottom of the screen that enables you to zoom in and out on the spreadsheet data instantly. The Backstage view attached to the File tab on the Excel Ribbon enables you to get at-a-glance information about your spreadsheet files as well as save, share, preview, and print them. Last but not least, Excel is full of pop-up galleries that make spreadsheet formatting and charting a real breeze, especially with the program’s Live Preview.

Before moving on, take a second to understand the difference between two terms that you see over and over in this book.

## 统计代写|excel代写代考|Checking Out Excel’s Start Screen

When you first launch Excel, the program welcomes you with an Excel Start screen similar to the one shown in Figure 1-1. This screen is divided into two panes.
The left green navigation pane with the Home icon selected contains New and Open items at the top and Account, Feedback, and Options at the bottom.

The right pane displays a single row of thumbnails showing some of the different templates you can use to create a new workbook at the top with a list of some of the most recently opened workbooks shown below. To see more templates to use in creating a new workbook, you can click either the More Templates link on the right side of the Home screen or the New icon in the navigation pane on the left.
If none of the Excel templates shown in the Home screen fit the bill, click More Templates (or click New in the Navigation pane) to open the New screen displaying a whole host of standard templates that you can select to use as the basis for new workbooks. These templates enable you to create a budget, track a project, create an invoice, and more. (See Book 2, Chapter 1 for more on creating new workbooks from ready-made and custom templates.)

To open an existing Excel workbook not displayed in the Recent list, click either the More Workbooks link on the lower-right side of the Home screen or the Open icon in the navigation pane on the left.

The first template thumbnail displayed on the top row of the Home tab on the Start screen is called Blank Workbook, and you select this thumbnail to start a new workbook of your own design.

When you first open a new, blank workbook by clicking the Blank Workbook thumbnail in the Home screen, Excel opens a single worksheet (with the generic name, Sheet1) in a new workbook file (with the generic filename, Book1) inside a program window such as the one shown in Figure 1-2.

When using Excel on a touchscreen device, the Ribbon Display Options are automatically set to Show Tabs Only (so that associated commands appear only when you tap a tab). To make it easier to select Ribbon commands with your finger or a stylus, click Ribbon Display Options (pointed out later in Figure 1-4) and then click Touch Spacing. With touch spacing engaged, Excel spreads out the tabs and their command buttons on the Ribbon. That way you have a fighting chance of correctly selecting them with your finger or stylus. On a touchscreen tablet, Excel automatically adds a Draw tab to the Ribbon containing loads of inking options that enable you to modify settings for drawing with your finger, a stylus, or a digital pen.

Excel 主要依赖称为功能区的屏幕元素，这是您选择绝大多数 Excel 命令的方式。此外，Excel 提供了一个工具栏（快速访问工具栏，默认情况下隐藏）、一些上下文相关的按钮和命令栏，这些按钮和命令栏以快速分析工具和迷你栏的形式出现，上下文选项卡仅在您使用选择某些 Excel 元素（例如表格或图像）以及许多任务窗格（例如剪贴板、研究、同义词库和选择等等）。

## MATLAB代写

MATLAB 是一种用于技术计算的高性能语言。它将计算、可视化和编程集成在一个易于使用的环境中，其中问题和解决方案以熟悉的数学符号表示。典型用途包括：数学和计算算法开发建模、仿真和原型制作数据分析、探索和可视化科学和工程图形应用程序开发，包括图形用户界面构建MATLAB 是一个交互式系统，其基本数据元素是一个不需要维度的数组。这使您可以解决许多技术计算问题，尤其是那些具有矩阵和向量公式的问题，而只需用 C 或 Fortran 等标量非交互式语言编写程序所需的时间的一小部分。MATLAB 名称代表矩阵实验室。MATLAB 最初的编写目的是提供对由 LINPACK 和 EISPACK 项目开发的矩阵软件的轻松访问，这两个项目共同代表了矩阵计算软件的最新技术。MATLAB 经过多年的发展，得到了许多用户的投入。在大学环境中，它是数学、工程和科学入门和高级课程的标准教学工具。在工业领域，MATLAB 是高效研究、开发和分析的首选工具。MATLAB 具有一系列称为工具箱的特定于应用程序的解决方案。对于大多数 MATLAB 用户来说非常重要，工具箱允许您学习应用专业技术。工具箱是 MATLAB 函数（M 文件）的综合集合，可扩展 MATLAB 环境以解决特定类别的问题。可用工具箱的领域包括信号处理、控制系统、神经网络、模糊逻辑、小波、仿真等。
