MATLAB integrates mathematical computing, visualization, and a powerful language to provide a flexible environment for technical computing. The open architecture makes it easy to use MATLAB and its companion products to explore data, create algorithms, and create custom tools that provide early insights and competitive advantages.

Simulink is an interactive tool for modeling, simulating, and analyzing dynamic, multidomain systems. It lets you build a block diagram, simulate the system's behavior, evaluate its performance, and refine the design. Simulink integrates seamlessly with MATLAB, providing you with immediate access to an extensive range of analysis and design tools. These benefits make Simulink the tool of choice for control system design, DSP design, communications system design, and other simulation applications.

This Williams College version of MatLab requires an on-campus network connection to connect to the license server. Use VPN software to use MatLab while off-campus.
