Path: Orbit/OrbitMechanics
% Compute continuous-time relative dynamics for Gauss' variational equations
The form is:
d/dt(del) = A(el)*del + B(el)*u
where A(el) is all zeros, except lower-left corner is -3n/2a,
n is the mean orbit rate, and u is the input acceleration with
x,y,z components in the radial, along-track, and orbit-normal
(or cross-track) directions, respectively.
