frame_transform_func Interface

interface
private subroutine frame_transform_func(mu, r, v, a, c, cdot)

Arguments

Type IntentOptional Attributes Name
real(kind=wp), intent(in) :: mu

gravitational parameter [km^3/s^2] [not used by all algorithms]

real(kind=wp), intent(in), dimension(3) :: r

position vector of target [km]

real(kind=wp), intent(in), dimension(3) :: v

velocity vector of target [km/s]

real(kind=wp), intent(in), optional, dimension(3) :: a

acceleration vector of target [km/s^2] (if not present, then a torque-free force model is assumed)

real(kind=wp), intent(out), dimension(3,3) :: c

C transformation matrix

real(kind=wp), intent(out), optional, dimension(3,3) :: cdot

CDOT transformation matrix
