◆ CheckRelinearizationFull()

static KeySet gtsam::UpdateImpl::CheckRelinearizationFull	(	const VectorValues &	delta,
		const ISAM2Params::RelinearizationThreshold &	relinearizeThreshold
	)

inlinestatic

Find the set of variables to be relinearized according to relinearizeThreshold. Any variables in the VectorValues delta whose vector magnitude is greater than or equal to relinearizeThreshold are returned.

Parameters

delta	The linear delta to check against the threshold
keyFormatter	Formatter for printing nonlinear keys during debugging

Returns: The set of variable indices in delta whose magnitude is greater than or equal to relinearizeThreshold

Definition at line 340 of file ISAM2-impl.h.

◆ CheckRelinearizationPartial()

static KeySet gtsam::UpdateImpl::CheckRelinearizationPartial	(	const ISAM2::Roots &	roots,
		const VectorValues &	delta,
		const ISAM2Params::RelinearizationThreshold &	relinearizeThreshold
	)

inlinestatic

Find the set of variables to be relinearized according to relinearizeThreshold. This check is performed recursively, starting at the top of the tree. Once a variable in the tree does not need to be relinearized, no further checks in that branch are performed. This is an approximation of the Full version, designed to save time at the expense of accuracy.

Parameters

delta	The linear delta to check against the threshold
keyFormatter	Formatter for printing nonlinear keys during debugging

Returns: The set of variable indices in delta whose magnitude is greater than or equal to relinearizeThreshold
