.. py:function:: intersection_ellipsoid_line(x, y, z, u1, u2, u3, a, b, c)

   Intersection of an ellipsoid defined by its axes a, b, c with the
   line p + λu.

   :param x: A point of the line
   :type x: float
   :param y: A point of the line
   :type y: float
   :param z: A point of the line
   :type z: float
   :param u1: The line vector
   :type u1: float
   :param u2: The line vector
   :type u2: float
   :param u3: The line vector
   :type u3: float
   :param a: The ellipsoidal axises
   :type a: float
   :param b: The ellipsoidal axises
   :type b: float
   :param c: The ellipsoidal axises
   :type c: float

   :returns: **p0, p1** -- This returns both of the points intersecting the ellipsoid.
   :rtype: numpy.ndarray


.. py:function:: project_point_on_ellipsoid(x, y, z, a, b, c)
