Terrestrial frame to topocentric North frame transformation matrix
[M] = CL_fr_topoNMat(orig)
Computes the frame transformation matrix M from the terrestrial reference frame to the local topocentric North frame.
By convention, multiplying M by coordinates relative to the terrestrial frame yields coordinates relative to the topocentric North frame.
Notes:
- The origin of the topocentric North frame is not the center of the planet, but the location defined by orig.
- This function can be used for another planet than the Earth.
See Local Frames for more details on the definition of local frames.
