As shown in the example I ponted to in another thread where the same
person asked the same question, there is actually no need to use Fmldivide
from C++, as it actually takes less effort to get the same result by invoking
the method Matrix::solve :

 Matrix A = args(0).matrix_value ();
 ColumnVector B = args(1).column_vector_value ();
 ColumnVector x = A.solve (B);
