Creation of TLE structure
tle = CL_tle_new([num])
This function creates a TLE structure with all fields initialized with default values. Epoch and orbital elements are set to %nan. The drag coefficient (bstar) is set to 0.
After the structure has been created, the values can be altered for instance by using CL_tle_set.
See Propagation models for more details.
Number of elements in the TLE structure. Default is 1
