I converted a function using matlab using matlab coder. in .m file i had declared:----
>> a.b = 37000; a.c = 8;
but as output in .c file i got:----
>>a.b=34000.0 a.c =7.0
? why has the values changed?

Could you include a simple code snippet that we can use to reproduce the issue. It might also help to mention the command you used to generate code, as well as the MATLAB version.

Do those variables happen to be loop control variables in a context where they are incremented by 3000 and 1 respectively before they are used?

As previously asked, can you post a code snippet and the command used to generate the code, so that we can reproduce the issue?

I echo the requests for more of the code. However, let me just point out that MATLAB Coder performs some optimizations. If you had code like this
n = 1;
if ~isreal(x)
n = n + 1;
end
You will probably see
n = 2.0;
generated if x is not real. Is it possible that after your assignment there are statements that the compiler can evaluate during compilation because the values/conditions are already known? -- Mike
