Package org.orekit.control.indirect.adjoint
This package provides routines to model the adjoint dynamics as in the Pontryagin Maximum Principle, as used
in indirect control. There is one adjoint variable for each dependent variable in the equations of motion (a.k.a. the state variables),
so in orbital mechanics that is typically the positionvelocity vector (or its equivalent e.g. orbital elements) and mass.
The adjoint vector is the solution to a differential system coupled with the state vector.
