While it is true at a fundamental level that computers are run by the binary logic of ones and zeros, it would be fairer to say that they really run on text. The raw text file has become the middle ground that is both understandable to the coder and easily parseable enough to be automatically converted into a form the machine can work with. This is true of the textual source code from which applications are generated, though in this case the conversion process is typically a one-shot event such that the program on your desktop contains only the computer-preferred binary code.

However there is a place where this distinction between the original source and the machine-usable form has not fallen away: the web. Every page opened in a browser is still in a human-readable form, encoded as HTML markup, and is translated into layout and text on the fly as the page is rendered.

A text file is inherently linear: one character following the next until the end of the file is reached. One could imagine how a page layout language could be devised that embraced this serial quality: turning the page into a list of commands to draw each line and place each picture. In fact this is the approach of the PostScript language used by high-end printers. However, HTML is different. Instead of being a procedural recipe for constructing the page, it is a declarative list with an elaborate structure defining what is contained inside of what. It is up to the browser to recognize this structure and interpret it as best it can. Again we see computers making allowances for humans and attempting to do what we mean rather than what we say.

But aside from the mechanics of constructing the document, the larger ecology of pages on the net is also interesting. Rarely does a document appear and remain forever unchanged. Freed from the costs of another print run, documents are edited repeatedly and updated imperceptibly. Leafnode attempts to show both the structure of the pages we create, and this process of evolution.

## 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。
