MathWorks Introduces Major New Releases of MATLAB and Simulink

Release 2012b Includes New Simulink Editor and MATLAB Desktop Features

Natick, Mass. - (12 Sep 2012)

The new Simulink Editor features simulation rewind, tabbed windows, and an Explorer bar

MathWorks today introduced Release 2012b with major updates to MATLAB and Simulink that significantly improve use and navigation. The new Simulink Editor features tabbed windows, smart signal routing and simulation rewind while the MATLAB Desktop now includes a toolstrip that offers quick access to frequently used features and a MATLAB apps gallery. In addition, Release 2012b includes a redesigned help system with improved browsing, searching, filtering, and content organization. For more details on Release 2012b, view these highlight videos.

New Look and Feel for Simulink

The new user interface and features for Simulink mark the beginning of a new era in Model-Based Design, which enables faster, more cost-effective development of dynamic and embedded systems. The Simulink Editor simplifies modeling through capabilities such as:

  • Tabbed model windows for improved window management
  • An Explorer bar for navigating model hierarchy 
  • Smart signal routing to determine optimal signal line path
  • Debugging capabilities that rewind simulations and set conditional breakpoints on signals

R2012b also introduces Simulink Projects for managing project files and connecting to source control software, and support for running models on target hardware such as Arduino, LEGO MINDSTORMS NXT, BeagleBoard, and PandaBoard.

New capabilities in Stateflow also simplify modeling. The Stateflow Editor is now unified with the Simulink Editor, and includes smart guides and transition indicator lines. Other features include state transition tables to model hierarchical state machines in a structured tabular form, and support for MATLAB as the action language for states and transitions.

Introducing New MATLAB Desktop Features

To help both new and experienced users navigate the continuously expanding capabilities within MATLAB, MathWorks has updated the MATLAB Desktop with two major enhancements:

  • The MATLAB Toolstrip displays icons for the most frequently used MATLAB features, such as selecting the best plot type for data
  • The apps gallery presents apps from the MATLAB product family to allow users to perform common tasks without writing code

Additional new features help users package MATLAB apps for inclusion in the gallery, import data from delimited and fixed-width text files using the Import Tool, and correct mistyped functions and variables in the Command Window.

New versions of MATLAB and Simulink are included in Release 2012b, which is available immediately. For additional information, see
