MATLAB Coder: Option "generate one file for each MATLAB file"

13 views (last 30 days)
Hello, I want to produce C/C++ standalone Code with MATLAB Coder. Although i took the option "generate one file for each MATLAB file" some MATLAB files are translated together in one C/C++ file. Is there another option to take influence on that? Kind regards Andreas

I tried this allready. So ist get a file for fcn2. But in fcn1 there is no call of fcn2. Fcn1 is y=x+1
I thing dividig code into single functions is the the best Way to structure and reuse your Code. If i get just one large C\C++ File with some hundrets of lines, there is noch Chance to Debug that anymore. Furthermore i think thats the Common way to write Code with many private funktions and only export some public ones.
What i don't unterstand is, that for some of the called not entry point functions a extra C-file is generated and for some not. Is there any way to influence that by some Coder Flag.

Thanks for following up. To prevent MATLAB Coder from inlining a function, you can use the line "coder.inline('never')". For example:
function b = fcn2(a)
b = a + 1;
This will prevent fcn2 from being inlined in fcn1.

Thank you.
The option coder.inline('never') was exactly, what i was searching for.

Possible solutions:
  1. Provide both functions as an entry-point function
  2. Use the coder.inline flag to control whether a function gets inlined (see documentation below)
