Real-Time Code Format

The real-time code format (corresponding to the generic real-time target) is useful for rapid prototyping applications. If you want to generate real-time code while iterating model parameters rapidly, you should begin the design process with the generic real-time target. The real-time code format supports:

• Continuous time
• Continuous states
• C MEX S-functions (inlined and noninlined)

For more information on inlining S-functions, see the Target Language Compiler Reference Guide.

The real-time code format declares memory statically, that is, at compile time.

Unsupported Blocks

The real-time format does not support the following built-in user-defined blocks:

• MATLAB Fcn (note that Simulink Fcn blocks are supported)
• S-Function -- M-file S-functions, Fortran S-functions, or C MEX S-functions that call into MATLAB (Simulink Fcn calls are supported).
