rt_nonfinite.h and rt_nonfinite.c are generated in different ways between matlab 2024 and matlab 2022 if I use the same configuration

Until now I have worked with Matlab 2022 for code generation with Embedded Coder, with this version the autogenerated file rt_nonfinite.c did not make use of the functions ‘isinf’ and ‘isnan’.

Using the Matlab 2024 version instead, the rt_nonfinite.c file makes use of these functions.

I cannot use a standard other than C99 so as not to have other problems with standard functions, such as fabs which assume the use of doubles, I would like to ask you if there is a setting to make the rt_nonfinite.c file be generated as it was with the 2022 version.

Hi @Emanuele,

I went through the documentation but I couldn't find anything mentioning to force the code generator to produce the old style of rt_nonfinite.c (i.e., without using isinf and isnan), as was done in MATLAB 2022. The code generation templates and support files are updated in newer releases, and MathWorks does not provide a built-in option to revert to legacy code patterns for this specific file.

Thank you very much, I was hoping for a different solution than replacing the generated files with a copy of those generated with Matlab 2022.
