_D_e_s_c_r_i_p_t_i_o_n:

     Creates an 'eulerzyx-class' object.

_U_s_a_g_e:

     eulerzyx(psi, theta, phi)

_A_r_g_u_m_e_n_t_s:

     psi: Rotation about Z axis 

   theta: Rotation about Y axis 

     phi: Rotation about X axis 

_D_e_t_a_i_l_s:

     The rotations are expressed in radians and applied in the order Z,
     Y, X.

     If 'theta' and 'phi' are missing, 'psi' is taken to be an n x 3
     matrix (or 3 element vector) holding all 3 Euler angles;
     alternatively, any orientation object may be used.

_V_a_l_u_e:

     An 'eulerzyx-class' object.

_A_u_t_h_o_r(_s):

     'skewvector', 'skewmatrix'

_E_x_a_m_p_l_e_s:
