  int m_row, n_col, l_pos;
  
  m_row = 1; n_col = 1; // We create a scalar
  CreateVar(1, MATRIX_OF_DOUBLE_DATATYPE, &m_row, &n_col, &l_pos);

  *stk(l_pos) = 1.0; // We store the value 1.0 in the area allocated by CreateVar

  LhsVar(1) = 1; // We set the parameter 1 created by CreateVar as an output parameter
                   // of the gateway function
