CL_co_car2sph — Cartesien to spherical coordinates
[pos_sph[,vel_geoc[,jacob]]] = CL_co_car2sph(pos_car[,vel_car])
Velocity geocentric coordinates and jacobien are optionnaly computed (velocity in cartesien coordinates needed).
Warning : pos_sph contains longitude, spherical latitude, and distance to center (whereas in elliptical coordinates it is longitude, elliptical latitude and elliptical altitude.
[X;Y;Z] positions in cartesien coordinates [m] (3xN)
(optional, needed for vel_geoc and jacob computation) [VX;VY;VZ] velocities in cartesien coordinates [m/s] (3xN)
[LON;LAT;D] positions in spherical (or geocentric) coordinates [rad],[m](3xN)
(optional) [LON;LAT;D] velocities in spherical (or geocentric) coordinates [rad/s],[m/s] (3xN)
(optional) transformation jacobian (6x6xN)
