netsse.simul.ship_resp.sum_components
=====================================

.. py:function:: netsse.simul.ship_resp.sum_components(aw, V_seed, W_seed, epsilon_seed, om_enc, time, seed, result, TRF_amps=0, TRF_phases=0, RespStr='Waves', AddNoise=False, snr=20)

   Performs the summation of the sine components to simulate in the time domain
   the encountered wave elevation or the wave-induced responses on a ship.

   :param aw: Amplitude of the wave components.
   :type aw: array_like of shape (Nfreq,Nbeta,1)
   :param V_seed: Standard normal distributed variables with mean 0 and std. 1.
   :type V_seed: array_like of shape (Nfreq,Nbeta,1)
   :param W_seed: Standard normal distributed variables with mean 0 and std. 1.
   :type W_seed: array_like of shape (Nfreq,Nbeta,1)
   :param epsilon_seed: Random phases [rad] of the wave components. Those are uniformly distributed
                        variables between 0 and :math:`2\pi`.
   :type epsilon_seed: array_like of shape (Nfreq,Nbeta,1)
   :param om_enc: Vector of encounter wave frequencies [rad/s].
   :type om_enc: array_like of shape (Nfreq,1,1)
   :param time: Vector of time [s].
   :type time: array_like of shape (1,1,Nt)
   :param seed: Index of the seed number.
   :type seed: int
   :param result: Anterior value of the vector of wave/response sequence.

                      Consult the documentation of the :func:`netsse.simul.ship_resp.simul_ship_resp`
                      function for information on the other parameters.
   :type result: array_like of shape (Nseed,Nt)

   :returns: **result** -- Updated value of the vector of wave/response sequence.
   :rtype: array_like of shape (Nseed,Nt)
