Detailed Description

Wrapper class to manage ISAM in a nonlinear context

Definition at line 29 of file HybridNonlinearISAM.h.

Constructor & Destructor Documentation

◆ HybridNonlinearISAM()

gtsam::HybridNonlinearISAM::HybridNonlinearISAM ( int  reorderInterval = 1,
const HybridGaussianFactorGraph::Eliminate eliminationFunction = HybridGaussianFactorGraph::EliminationTraitsType::DefaultEliminate 
)
inline

Periodically reorder and re-linearize

Parameters
reorderIntervalis the number of updates between re-orderings, 0 never reorders (and is dangerous for memory consumption) 1 (default) reorders every time, in worse case is batch every update typical values are 50 or 100
