- Major enhancements to the FFT, IFFT, Magnitude FFT, Overlap-Add
FFT, Overlap-Save FFT, Random Source, Sine Wave, Unwrap, and
Window Function blocks
- Additional data type support of Simulink built-in data types, fixed-point
data types, and custom data types
- Improved memory management for both simulation and Real-Time
Workshop C code generation
- Smaller, more efficient Real-Time Workshop generated code
•Extensible C-callable simulation and run-time library functions, macros,
and definitions for use with your S-functions and Real-Time Workshop C
code
