Key Additions and Improvements

New Products

• MATLAB Test – A framework for developing, executing, measuring, and managing MATLAB code testing at scale. It supports test grouping, code coverage metrics (including MC/DC), and provides a dashboard for visualizing results.
• C2000 Microcontroller Blockset – Adds support for designing, simulating, and implementing applications for Texas Instruments C2000 MCUs. Includes peripheral blocks for ADC, PWM, and digital IO, with synchronized control algorithm simulations for motor and power control.

Major Toolbox and Blockset Updates

• Aerospace Blockset – Expanded high-fidelity modeling and simulation for aircraft, rotorcraft, and spacecraft, including pilot behavior, actuators, and propulsion.
• Communications Toolbox – Enhanced features for wireless system design, including MIMO, OFDM, and channel coding.
• Powertrain Blockset – New reference architectures for internal combustion, hybrid, fuel-cell, and electric vehicle powertrains.
• Vehicle Dynamics Blockset – Added models for cars, trucks, and two-wheelers, with expanded steering, braking, and suspension libraries.
• Additional improvements were made to Phased Array System Toolbox, SerDes Toolbox, Simulink Control Design, and ROS Toolbox, supporting advanced simulations across multiple domains.

MATLAB & Simulink Workflow Enhancements

• Live Editor tasks for data import and trend removal make common analysis steps more interactive.
• New pivot function for summarizing and analyzing tabular data.
• Code Analyzer App and the fix function for automatically identifying and resolving coding issues.
• Improved Python integration with better data type handling and support for Python objects as dictionary keys.
• Enhancements to table and timetable data types, including in-place computations and event labeling.
• Integrated unit testing tools with a Test Browser for managing and debugging tests.
• Simulink Enhancements:
  • Step-through simulation debugging at the block level.
  • Direct importing of Python functions into Simulink models.
  • Better signal logging with support for variable-size signals in buses and arrays.
