Matrix operations on matrix signals are now supported for several blocks. Ada S-functions are supported. Note The Simulink Performance Tools , introduced with Release 12, provide additional tools for working in the Simulink environment, including a Simulink Accelerator for faster simulation of models, via compiled code, as well as a Model Profiler, Model Differences tool, and a Test Coverage tool. You can now initialize all Stateflow data to the workspace and copy it back to the workspace at the end of a simulation. ROM and RAM size rivals hand-written code.
Code generation is faster.
The new temporal logic feature is supported. Enhancements include support for singletasking, multirate models. The Simulink blocks formerly included in the Communications Toolbox now form the basis of a separate product, the Communications Blockset. The Data Acquisition Toolbox 2.0 now supports ComputerBoards hardware. Easier generation and processing of matrix signals Frame-based signals support and matrix signals support has been added to many blocks.
