MATLAB是一种科学计算软件，专门以矩阵的形式处理数据。MATLAB将高性能的数值计算和可视化集成在一起，并提供了大量的内置函数，从而使其被广泛地应用于科学计算、控制系统、信息处理等领域的分析、仿真和设计工作中，而且利用MATLAB产品的开放式结构，用户可以非常容易地对MATLAB的功能进行扩充，从而在不断深化对问题认识的同时，逐步完善MATLAB产品以提高产品自身的竞争能力。 (MATLAB is a scientific computing software, and specialized form of a matrix data processing. MATLAB will be high-performance numeric computation and visualization integrated and provides a number of built-in function, so that it is widely used in scientific computing, control systems, information processing, analysis, simulation and design work , and the use of the open architecture of MATLAB product, the user can very easy expansion of the MATLAB functions, thus deepening the understanding of the problem, and gradually perfect the MATLAB products to enhance the competitiveness of the product itself.)
