Details:

Take the following MEX-function:


void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
    plhs[0] = mxCreateNumericArray(0, NULL, mxDOUBLE_CLASS, mxREAL);
}


and run it:


>> out = my_mex_test();


In Octave, this creates a scalar array initialized to 0,
i.e size(out) = [1 1], similar to double(0)

In MATLAB, this creates an empty array,
i.e size(out) = [0 0], similar to double([])

I'm using the official Octave installer, and the latest MATLAB R2015a.
