DEFUN_DLD(matMult,args, , "Test function.")
{
   octave_value_list retval;

   ComplexMatrix a(args(0).complex_matrix_value());

   Matrix b(args(1).matrix_value());

   ColumnVector c(args(2).vector_value());

   retval(2) = octave_value(c);

   retval(1) = octave_value (b)

   retval(0) = octave_value (a);

   return retval;
}
