-- 1.什么是MATLAB --
MATLAB是matrix&laboratory两个词的组合，意为“矩阵工厂”，软件主要面对科学计算、可视化以及交互式程序设计的高科技计算环境。
MATLAB is a combination of the words matrix & laboratory, meaning "matrix factory", and the software is mainly exposed to the high-tech computing environment of scientific computing, visualization and interactive programming.
它将数值分析、矩阵计算、科学数据可视化以及非线性动态系统的建模和仿真等诸多强大功能集成在一个易于使用的视窗环境中，为科学研究、工程设计以及必须进行有效数值计算的众多科学领域提供了一种全面的解决方案，并在很大程度上摆脱了传统非交互式程序设计语言的编辑模式。
It integrates powerful features such as numerical analysis, matrix computation, scientific data visualization, and modeling and simulation of nonlinear dynamic systems in an easy-to-use window environment, providing a comprehensive solution for scientific research, engineering design, and the many scientific fields where efficient numerical computations must be performed, and largely moving away from the editing mode of traditional non-interactive programming languages.
