Thanks for the tip, I'll check it out.

No, GeographicLib doesn't contain any routines for matrix and vector algebra. I recommend you use Eigen for this purpose. It's capable and, as a header-only package, easy to incorporate into your project.

Hi, I realize this is an old question, but I'm looking to do something similar as well. I realize this is not part of the Geographiclib API, but are there classes within the library to use to accomplish this? I'm working on a project where I have Geographiclib for some things, and some other matrix and vector classes that I use primarily to accomplish my orientation conversions. I'd really like it if I could get rid of all those other classes and just use Geographiclib, if possible. Can I do those...

Sorry to be so late answering this... The documentation in the C++ library explains how to interpret the azimuth at one of the poles: If either point is at a pole, the azimuth is defined by keeping the longitude fixed, writing latitude = ±(90° − ε), and taking the limit ε → 0+. Let me know of you have further questions.
