Description

Declares routines to operate on 3x3 matrices that are boxes, ie. have zero values in their upper right triangle.

This header is distinct from matrix.h so that we can still inline these operations while not requiring headers that merely need the name Matrix3x3 to pull in the dependencies needed here.
