Start MATLAB Product Description The Language of Technical Computing Millions of engineers and scientists worldwide use matlab to analyze and design the systems and products transforming our world. MATLAB is in automobile active safety systems, interplanetary spacecraft, health monitoring devices, smart power grids, and LTE cellular networks. It is used for machine learning, signal processing, image processing, computer vision, communications, computational finance, control design, robotics and much more Math. Graphics Programming. The MatlaB platform is optimized for solving engineering and scientific problems. The matrix-based MATLAB language is the world's most natural way to express computational mathematics. Built-in graphics make it easy to visualize and gain insights from data. A vast library of pre-built toolboxes lets you get started right away with algorithms essential to your domain. The desktop environment invites experimentation, exploration, and discovery. These matlab tools and capabilities are all rigorously tested and designed to work together Scale. Integrate. Deploy. MAtLAB helps you take your ideas beyond the desktop You can run your analyses on larger data sets, and scale up to clusters and clouds. mATLAB code can be integrated with other languages, enabling you to deploy algorithms and applications within web enterprise, and production systems Key Features High-level language for scientific and engineering computing Desktop environment tuned for iterative exploration, design, and problem-solving Graphics for visualizing data and tools for creating custom plots Apps for curve fitting, data classification, signal analysis, control system tuning, and many other tasks Add-on toolboxes for a wide range of engineering and scientific applications Tools for building applications with custom user interfaces Interfaces to C/C++, Java,. NET, Python, SQL, Hadoop, and Microsoft@ Excel@ 1-2
