public void partialsComputed(SpacecraftState state, double[] factor, double[] accelerationPartials)
Callback called when partial derivatives have been computed.The factor matrix is: \[F = \begin{matrix} 0 & 0 & 0 & 1 & 0 & 0 \\ 0 & 0 & 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & 0 & 0 & 1 \\ \sum \frac{da_x}{dp_x} & \sum\frac{da_x}{dp_y} & \sum\frac{da_x}{dp_z} & \sum\frac{da_x}{dv_x} & \sum\frac{da_x}{dv_y} & \sum\frac{da_x}{dv_z}\\ \sum \frac{da_y}{dp_x} & \sum\frac{da_y}{dp_y} & \sum\frac{da_y}{dp_z} & \sum\frac{da_y}{dv_x} & \sum\frac{da_y}{dv_y} & \sum\frac{da_y}{dv_z}\\ \sum \frac{da_z}{dp_x} & \sum\frac{da_z}{dp_y} & \sum\frac{da_z}{dp_z} & \sum\frac{da_z}{dv_x} & \sum\frac{da_z}{dv_y} & \sum\frac{da_z}{dv_z} \end{matrix}\]
