Simulink S-Functions

The -W simulink -L C options produce a Simulink S -function wrapper.

Simulink S-function wrappers conform to the Simulink C S-function

conventions. The wrappers initialize:

•The

sizes structure

•The S-function’s sample times array

•The S-function’s states and work vectors

•The global variables and constant pool

For more information about Simulink S-function requirements, see Writing

S-Functions.

Note By default, the -S command does not include any functions that do not

appear on the command line. Functions that do not appear on t he command

line would generate a callback to MATLAB. S pec ify

-h if you want all

functions ca lle d to be compile d into your MEX - fi le.

C Libraries

The intent of the C library wrapper files is to allow theinclusion of an arbitrary

set of M-files into a static library or shared library. The header file contains all

of the entry points for all of the compiled M functions. The e xport list contains

the set of symbols that are exported from a C shared library.

Another benefit of creating a library is that you can compile a common set of

functions once. You can then compile other M-functions that depend on them

withoutrecompilingtheoriginalfunctions.You can accomplishthisusing

mlib

files, which are automatically generated when you generate the library. For

more information about

mlib files, see “mlib Files” on page 5-25.

Note Even if you are not producing a shared library, you must generate a

library wrapp er file w h en includ ing any C ompiler-generate d cod e into a larger

application.
