Hi guys, currently on a holiday in Scotland, and without my ESP32 here I'm doing some research online for when I get back home again.

I'm reading up on Kalman filters, and trying to figure out how I can implement one on the ESP32 to handle the sensors on my autonomous RC car. When reading about Kalman filters I see they rely on math using matrices (matrix), so I spun off and googled about C++ and matrices. There I discovered the Eigen library (http://eigen.tuxfamily.org).

Do you know if it is possible to use Eigen on the ESP32 to do matrix calculations?

I do not have experiences implementing Kalman filters, but followed some discussions on Hacker News. The hard part is not necessarily implementing them (not easy either) but that they are notoriously difficult to tune, so if you are more interested in the result than the process I would recommend going for chips that handle all that for you.
