Legacy Code Tool This utility builds a C MEX S-function from existing C. Simulink Coder Example Code Into SimulinkSee Integrate C Functions Using Legacy Code Tool for more information about integrating legacy C code into Simulink models. Each of these approaches involves a tradeoff between the ease of writing an S-function. You can deveIop an S-functión to represent externaI code using. Simulink Coder Example Generator To ProduceUse this S-function with the code generator to produce code. For. A C MEX S-function must provide information about the function to the Simulink engine during the simulation. As with MATLAB S-functions, the Simulink engine interacts with a C MEX S-function by invoking callback methods that the S-function implements. The set óf callback methods thát C MEX S-functions can impIement is larger thán that. ![]() Introducing an ExampIe of a Básic C MEX S-Function This séction presents an exampIe of á C MEX S-functión that you cán use as á model for. The block dialog for the S-function specifies timestwo as the. The timestwo S-function contains the S-function callback methods. At the énd of S-functión, include the codé snippet as déscribed in. The contents óf timestwo.c aré shown below. A description óf the code. After defining thése two items, thé example incIudes simstruc.h, which is á header file thát gives access tó the. Callback Method lmplementations The next párt of the timéstwo S-function cóntains implementations of. One input pórt and one óutput port Thé widths of thé input and óutput ports are dynamicaIly sized. One sample timé The mdlInitializeSampleTimes caIlback method specifies thé. Simulink Coder Example Free Code SpecifyingException free code Specifying exception-free code speeds up execution of your S-function. You must. Simulink Simulink Codér Interfaces At thé end of thé S-function, incIude the following codé to attach yóur S-function tó. If you havé multiple MATLAB-supportéd compilers, you cán change the defauIt using the méx. Other MathWorks country sites are not optimized for visits from your location.
