I am using MATLAB coder to try and make an executable function; however, after generating the C source file for the function the code just looks like below.
void testscriptfunc(real_T i)
{
(void)i;
/* comments */
}
It seems to skip all the code in my function and only generates anything I have commented out in the function ias a comment in the C code. When I try generating the code as a MEX function using C it seems to work correctly but when generating any source code it generates something like the code above. Does anyone have any ideas as to what could be causing this?

Perhaps the function returns nothing and has no side effects, then the complete source code could be optimized away.

Hi Grant,
This usually happens when if the function in question does not return anything and has no other side-effects. In this case the MATLAB coder wil optimize the entire function.
Hope this helps!
