Released October 9, 2008

What's New in Release 2008b

Release 2008b includes new features in MATLAB and Simulink, two new products, and updates and bug fixes to 91 other products, including PolySpace code verification products. Subscribers to MathWorks Software Maintenance Service can download product updates.

Since R2008a, the MATLAB and Simulink product families require activation. R2008b includes enhancements to the License Center, the online tool for managing your license and user information.

New capabilities for the MATLAB product family include:

New capabilities for the Simulink product family include:

  • MATLAB based language in Simscape for authoring of physical modeling components
  • Fixed-point data types up to 128 bits for accelerated simulation, automatic code generation, Embedded MATLAB code, and Simulink Fixed Point
  • Support for embedding Simulink function-call subsystems in Stateflow charts
  • Target-specific code generation for Embedded MATLAB code, and generation of encapsulated C++ class interfaces, in Real-Time Workshop Embedded Coder
  • CD and network boot options and real-time Ethernet I/O support in xPC Target
  • SimElectronics, a new product for modeling and simulating electronic and electromechanical systems
