MATLAB: Is it possible to put C++ code on a .m for help MATLAB Coder to traduce

matlab coder

Hello,
I use Matlab Coder and i use the function coder.ceval for use C++ function when i generate my C++ code.
But Matlab make a lot of error (use the value of the variable instead the name variable …)
So i search to know if it is possible to put directly the C++ code on the .m instead use coder.ceval for have the good code C++ after the generation with Matlab Coder ?
For example : I use
If isempty(coder.target)
Texte=int2str(Variable);
else
coder.ceval(sprintf,Texte,'"%d"',Variable);
end
But Matlab Coder make some error, i would use something like this :
If isempty(coder.target)
  Texte=int2str(Variable);
  else
    A_Function('sprintf(Texte,"%d",Variable);');
    end
Do you know if somethings like that exist ? Thank you for your help.

Best Answer

I think you need single quotes around your function name (sprintf), because the first argument to coder.ceval is the string containing the C-function that you want to call.
if isempty(coder.target)
  Texte=int2str(Variable);
else
  coder.ceval('sprintf',Texte,'"%d"',Variable);
end
This should generate a call to sprintf as you expect.
