I want to use the out-of-process functionnality and to return an empty array in my C++ mexFunction.

It is not exactly the same question as :

since it is in C++ and with feval.

Here the problem:

void MexFunction::operator()(mm::ArgumentList outputs, mm::ArgumentList inputs)
{
	outputs[0] = f.createEmptyArray();
}

that i called with

>> mh = mexhost; res = feval(mh,'example');
Error using matlab.mex.MexHost/feval
Too many output arguments.

but directly called via the Command window I have:

>> example
ans =
     []

I'm facing the same problem, any update?
