Parameters:

• i (int) – Index of the mode.

• u (1darray) – Array of modal coefficient.

• ordered (TYPE, optional) – Regulates how mode are ordered. If True, they are ordered for decreasing effective index. If Flase, the order is whatever is returned by the diagonalization routine. Defaults to True.
