% Closed form solution of relative orbital motion using Hills equations.
Since version 7.
--------------------------------------------------------------------------
Form:
X = HillsEqns( Xo, w, t, flag )
--------------------------------------------------------------------------
------
Inputs
------
Xo (6,nSC) Initial state in Hills frame, length unit [L], velocity unit [L/sec]
* each column is the state of a s/c, [x; y; z; xdot; ydot; zdot]
w (1) Orbital Rate (rad/s)
t (:) time vector (sec)
flag (1,1) If entered, the output is formatted as a (6,nSC) matrix.
-------
Outputs
-------
X (nSC).r Position field, (3,:) matrix
.v Velocity field, (3,:) matrix
.t Time field, (1,:) vector
