MathWorks introduced Release 2021b of the MATLAB and Simulink product families. Release 2021b (R2021b) offers hundreds of new and updated features and functions in MATLAB® and Simulink®, along with two new products and five major updates. New capabilities in MATLAB include code refactoring and block editing, as well as the ability to run Python commands and scripts from MATLAB.  Simulink updates enable users to run multiple simulations for different scenarios from the Simulink Editor and to create custom tabs in the Simulink Toolstrip.  

R2021b also introduces new products supporting wireless communications:  

•    RF PCB Toolbox 

RF PCB Toolbox enables the design, analysis, and visualization of high-speed and RF multi-layer printed circuit boards (PCBs). RF engineers can design components with parameterized or arbitrary geometry, including distributed passive structures such as traces, bends and vias. Using the frequency-domain method of moments and other EM techniques, coupling, dispersion and parasitic effects can be modeled. Toolbox support for ODB++ and databases from Cadence® Allegro®, Mentor Expedition, Altium®, and Zuken enables signal integrity engineers to analyze the high speed portions of the PCB layout. 

•    Signal Integrity Toolbox

Signal Integrity Toolbox provides functions and apps for designing high-speed serial and parallel links.  Users can generate experiments covering multiple parameters, extract design metrics and visualize waveforms and results.  The toolbox supports standard-compliant IBIS-AMI models for statistical and time-domain simulation to analyze equalization and clock recovery. 

In addition to the new products, R2021b includes major updates to Symbolic Math Toolbox, Lidar Toolbox, and Simulink Control Design and other products in the areas of deep learning, reinforcement learning, predictive maintenance and statistics and machine learning. R2021b is available immediately worldwide.
