Determine whether model has changed since it was loaded
Changed = slIsFileChangedOnDisk('sys')
Changed = slIsFileChangedOnDisk('sys') Returns true if the file which contains block diagram sys was changed on disk since the block diagram was loaded.
To ensure that code is not generated for a model whose file has changed on disk since it was loaded, include the following in the 'entry' section of the STF_make_rtw_hook.m file:
if (slIsFileChangedOnDisk(sys)) error('File has changed on disk since it was loaded. Aborting code generation.'); end
