% Determine the target state on the desired trajectory that gives the minimum
time-weighted cost.
Use the LPEccentric control algorithm to compute the delta-v's associated with
maneuvering from an initial state (x0) to a series of target states, which
lie on a trajectory defined by the geometric goals (g). The target state
associated with the minimum time-weighted cost is returned.
Since version 7.
