Hello, I generate a code from my model.

The generated code use function like: fmodf and floorf that are part of math.h but in C99 version.

My compiler doesn't support these functions.

How can I Force Matlab to use C90 corresponding function (fmod and floor) instead?

I'm using version 2016b.

Answer 1

In my understanding you are trying to generate code using C90 type. In general, MATLAB coder uses C89/C90 (ANSI) types by default.

You can explicitly change the 'Standard math library' property to 'C89/C90 (ANSI)' in Custom Code tab during code generation.

Take a look at the following documentation Change the Standard Math Library for detailed information.
