Generating B\'ezout trees for Pythagorean pairs

Relatively prime pairs of integers can be represented as nodes in three way branching trees. We construct trees of B'ezout coefficients which correspond to the relatively prime pairs in the aforementioned trees. As one application, we compare the B'ezout coefficients in these trees to those returned by the gcd function in Matlab. As another application, we use these trees to decrease the computation time required to create computer generated hyperbolic wallpaper designs.
