GTSAM is an optimization library for objective functions expressed as a factor graph over a set of unknown variables. In the continuous case, the variables are typically vectors or elements on a manifold (such as the 3D rotation manifold). The factors compute vector-valued errors that need to be minimized, and are typically only ...
