$$E(x) := \frac{x_1^2}{e_1^2} + \frac{x_2^2}{e_2^2} + \frac{x_3^2}{e_3^2} - 1 = 0$$
Let $y$ be a point outside the ellipsoid:
$$y = \begin{bmatrix} y_1 \\ y_2 \\ y_3 \end{bmatrix}$$
For any point
$x$ $x = \begin{bmatrix} x_1 & x_2 & x_3 \end{bmatrix}^{T}$ on the ellipsoid we have:
$$y - x = \frac{1}{2} t \nabla E(x)
= t \begin{bmatrix}
\frac{1}{e_1^2} && \\
