Orbital perturbation - J2 perturbation

Original two-body orbital motion equation (ODE)

dRVdt = twoBodyOde(t, RV, mu)

$J_2$ equation of two body orbital motion under perturbation

1. Average Method:

[rt, vt] = rv02rvf_aveJ2(r0, v0, dt, mu, Re)

2. Exact $J_2$ perturbation (ODE)

dRVdt = twoBodyJ2Ode(t, RV, mu, Re)

The ODE equations please use MATLAB to solve the ODE solver ode45 (recommended).
