% Compute the gravitational acceleration in spherical coordinates.
Acceleration vectors are a [ a(r), a(lambda), a(theta) ].
The coefficients should be unnormalized. If they are not the function will
throw a warning and unnormalize them.
[s, c, j, mu, a] = LoadGEM( 1 )
for k = 1:kMax
[a, aS, aZ, aT] = AGravity( nZ, nT, r, lambda, theta, s, c, j, mu, a );
end
than
for k = 1:kMax
[a, aS, aZ, aT] = AGravity( nZ, nT, r, lambda, theta );
end

Form:
[aG, aS, aZ, aT] = AGravity( nZ, nT, r, lambda, theta, d )
[aG, aS, aZ, aT] = AGravity( nZ, nT, r, lambda, theta, s, c, j, mu, a )
