How to use varargout function with matlab coder?
显示 更早的评论
Hi, i'm trying to convert my Matlab script into C with Matlab Coder app but i'm having a problem, when app get into the "Check for Run-Time Issue" window it tells me: Top-level function cannot have varargout.
I'm not a programer so i have only basic knowledge. How can i procede to overcome this issue?
Thks!

Starting in MATLAB R2017b, MATLAB Coder supports varargout in entry-point functions. The documentation:
https://www.mathworks.com/help/coder/ug/specify-number-of-input-or-output-arguments-to-generate.html
covers this in more detail.
In earlier releases, you can have a wrapper with explicit output arguments. So if you are trying to generate code for
function varargout = entryPoint(a,b,c)
...
end
you can instead use
function [out1,out2,out3] = entryPointWrapper(a,b,c)
[out1,out2,out3] = entryPoint(a,b,c);
end
and generate code from entryPointWrapper.

Yep, the second option, using a wrapper function without varargout, is the best way forward.
That said, looking at your script since there is a lot of plotting and graphics, MATLAB Coder isn't the best tool. As Kojiro Saito and Fred Smith and said in your other question:
MATLAB Compiler would be a better tool for your application because of the plotting/app code.
