MATLAB® 是一种用于数值计算、可视化及编程的高级语言和交互式环境。使用 MATLAB，可以分析数据，开发算法，创建模型和应用程序。借助其语言、工具和内置数学函数，您可以探求多种方法，比电子表格或传统编程语言（如 C/C++ 或 Java™）更快地获解。

MATLAB 应用广泛，包括信号处理和通信、图像和视频处理、控制系统、测试和测量、计算金融学及计算生物学等众多应用领域。在各行业和学术机构中，有超过一百万工程师和科学家使用 MATLAB 这一技术计算语言。

MathWorks于本日（2012-09-12）推出 Release 2012b，其中该版本具有 MATLAB 和 Simulink 的重大更新，可显著提升用户的使用与导航体验。新增的 Simulink 编辑器采用选项卡式窗口，并且支持信号线智能布控和仿真回退;MATLAB 桌面则新添了一个工具条，以方便用户快速访问常用功能和 MATLAB 应用程序库。此外，Release 2012b 中还含带了经过重新设计的帮助系统，改进了浏览、搜索、筛选和内容分类。

Release 2012b includes major new releases of MATLAB and Simulink, featuring the new MATLAB Desktop, Simulink Editor, and Documentation Center. In addition, there is one new product and updates and bug fixes to 81 other products.

MATLAB and Simulink are used throughout the automotive, aerospace, communications, electronics, and industrial automation industries as fundamental tools for research and development. They are also used for modeling and simulation in increasingly technical fields, such as financial services and computational biology. MATLAB and Simulink enable the design and development of a wide range of advanced products, including automotive systems, aerospace flight control and avionics, telecommunications and other electronics equipment, industrial machinery, and medical devices. More than 5000 colleges and universities around the world use MATLAB and Simulink for teaching and research in a broad range of technical disciplines.
