Fixed-frame coordinates from center of planet, specified as an N-by-3 matrix, in selected units. Each row of the matrix is a separate position to calculate. In reality, Earth is not exactly spherical, mainly because of its rotation around the polar axis that makes its shape slightly oblate. If this shape were perfectly known together with the exact mass density ρ = ρ(x, y, z), the integrals (1) and (2) could be evaluated with numerical methods to find a more accurate model for Earth's gravitational field. However, the situation is in fact the opposite.
