Follow-up Comment #7:

Could 3D vectors also be derived by e.g., geodetic2ecef using a spherical
geoid? (just curious)
Matlab makes it a bit difficult by requiring one set of coordinates + azimuth
values per circle; I was thinking maybe great circles input could also be
specified using pairs of non-antipodal coordinates, as a sort of Octave-only
extension. I have use cases for such occasions. But hmm, maybe later.

Anyway I think you did a fine job, nice!

I'll see if the check for coinciding great circles can be vectorized a little
more and I'll ass a few more tests for vector inputs.
IMO the coincidental circles warning might need a "\n" at the end to suppress
the backtrace (although Matlab supplies that as well).
I'll also add a stanza in the texinfo about coinciding circles.

Do you also plan to supply gcxsc, scxsc and rhxrh ?

FYI the functionality of polyxpoly is already present in the geometry package,
only a wrapper would be required.
