Detailed Description

A junction tree specialized to Gaussian factors, i.e., it is a cluster tree with Gaussian factors stored in each cluster. It can be eliminated into a Gaussian Bayes tree with the same structure, which is essentially doing multifrontal sparse matrix factorization.

Constructor & Destructor Documentation

◆ GaussianJunctionTree()

gtsam::GaussianJunctionTree::GaussianJunctionTree ( const GaussianEliminationTree eliminationTree)

Build the elimination tree of a factor graph using pre-computed column structure.

Parameters
factorGraphThe factor graph for which to build the elimination tree
structureThe set of factors involving each variable. If this is not precomputed, you can call the Create(const FactorGraph<DERIVEDFACTOR>&) named constructor instead.
Returns
The elimination tree
