gtsam::Scatter Class Reference

Detailed Description

Scatter is an intermediate data structure used when building a HessianFactor incrementally, to get the keys in the right order.

In spirit, it is a map from global variable indices to slot indices in the union of involved variables. We also include the dimensionality of the variable.

Public Member Functions
	Scatter ()
	Default Constructor.
	Scatter (const GaussianFactorGraph &gfg, boost::optional< const Ordering & > ordering=boost::none)
