FFEccDZ:

Path: FormationFlying/Derivatives

% Compute the first derivative of z with respect to true anomaly.
   This is used by the FFEccZExt function.

   Since version 7.

   nu               (1)   True anomaly [rad]
   e                (1)   Eccentricity
   D               (6,1)  Integration constants computed from i.c.'s
   dH               (1)   Integration constant computed from H(nu0)=0

   -------
   Outputs
   -------
   dz               (1)   First derivative of z with respect to true anomaly
