How to generate emxAPI.h and emxutil.h files on MATLAB Coder?

Hello, my assignment requires me to use MATLAB Coder to generate some files. I didn't install the entirety of the MATLAB app library during installation because I do not have enough space. Does anyone know which apps make the emxAPI.h and emxutil.h files?

Hi Deo Kim,

I understand, you want to use emxAPI.h and emxutil.h files with MATLAB but you haven't installed the entire app library due to the limited space you have in your computer.

The emxAPI.h and emxutil.h files are typically generated by the MATLAB Coder app. MATLAB Coder is a standalone product that provides an interactive environment for generating C/C++ code from MATLAB code.

You can go on the APPs menu in MATLAB, click on the Install App button, search for MATLAB coder and install it from there.

For generating the emxAPI.h file and emxutil.h files, you can checkout this documentation on how you can include c/c++ header files

Yeah, I know they are generated by MATLAB Coder, I am wondering which additional application generates those files in addition to the files already generated by MATLAB Coder.

Hi Deo,

I am only aware of 2 major code generation applications in MATLAB (MATLAB coder and DSP toolbox).

If you want to learn more about the DSP toolbox, you can click on the following link,

Thank you for your response, but the app DSP System Toolbox and DSP HDL Toolbox did not generate the emxAPI.h file and emxutil.h files in MATLAB Coder.
