MathWorks Unveils Release 2021a of MATLAB and Simulink

MathWorks has introduced the newest release of the MATLAB and Simulink product families. Release 2021a (R2021a) offers hundreds of new and updated features and functions in MATLAB and Simulink, along with three new products and 12 major updates.

New capabilities in MATLAB include dynamic controls in live scripts as well as a new task for adding plots to live scripts without writing any code. Simulink updates enable users to import C code as reusable Simulink libraries and to speed up simulations. R2021a also introduces new products in the areas of satellite communications, radar, and DDS applications.

New products introduced in R2021a are:

  • Satellite Communications Toolbox: As the number of low earth orbit (LEO) satellites increases to serve the high-speed mobility market, Satellite Communications Toolbox is designed to help equipment makers and operators model, simulate, analyze, and verify satellite communications systems and links. The new toolbox provides a flexible environment in MATLAB for developing standards-based satellite communications signals, and configurability and extensibility for multi-domain simulation and verification of satellite communication, navigation, and remote sensing systems.
  • Radar Toolbox: Radar Toolbox includes algorithms and tools for the design, simulation, analysis, and testing of multifunction radar systems. As a result, radar system designers and integrators can assess system design trade-offs before radars are built or procured. Starting with R2021a, radar specific capabilities and examples previously found in Phased Array System Toolbox will be found in the new Radar Toolbox.
  • DDS Blockset: The new Simulink add-on, DDS Blockset, gives system and algorithm engineers developing software for DDS-based embedded systems a full Model-Based Design experience featuring modeling, simulation, verification, and code generation. As a result, engineers find errors much sooner while performing faster design and coding iterations.

In addition to the new products, R2021a includes updates to Polyspace, Stateflow, and other products in the areas of autonomous systems, computational finance, control systems, image processing and computer vision, RF and mixed-signal, and test and measurement. R2021a is available immediately worldwide.
