jaxlie documentation

   

jaxlie is a Lie theory library for rigid body transformations and optimization in JAX.

Current functionality:

• SO(2), SE(2), SO(3), and SE(3) Lie groups implemented as high-level dataclasses.

• exp(), log(), adjoint(), multiply(), inverse(), and identity() implementations for each Lie group.

• Pytree registration for all dataclasses.

• Helpers + analytical Jacobians for tangent-space optimization (jaxlie.manifold).
