How to recompile S-functions in Simulink?

When executing my Simulink program, containing S-functions, I get the following error:

To use block 'Environnement/S-Function' in referenced models, recompile the S-function with the current version of Simulink.

The S-function I'm trying to use is one I downloaded, but I changed the code and made a new function with the new code.

How can I recompile this S-function and get rid of this error?

Thanks

Hi Laurent,

I am guessing you have edited the C S-Function. Once you have changed the C S-Function, you have to mex it inorder to compile and use in Simulink as a block. The command is

>>mex filename.c

Refer this link for an example.

Hope this helps, Abhishek
