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.
