netsse.model.ship.heaveCF
=========================

.. py:function:: netsse.model.ship.heaveCF(om0, beta_deg, U, L, B0, T, C_B=1)

   Computes the heave transfer function amplitude, using the closed-form
   expressions presented in Jensen et al. (2004).

   :param om0: Vector of absolute wave frequencies [rad/s].
   :type om0: array_like of shape (Nom0,)
   :param beta_deg: Vector of heading angles [deg].
   :type beta_deg: array_like of shape (Nbeta,)
   :param U: Vessel forward speed [m/s].
   :type U: float
   :param L: Length of the ship [m].
   :type L: float
   :param B0: Breadth of the ship [m].
   :type B0: float
   :param T: Draft of the ship [m].
   :type T: float
   :param C_B: Block coefficient of the ship [-].
   :type C_B: float, default 1

   :returns: **heave** -- Coefficients of the heave transfer function amplitude [m/m].
   :rtype: numpy.ndarray of shape (Nom0,Nbeta)
