Detailed Description

This class performs Gauss-Newton nonlinear optimization

Definition at line 38 of file GaussNewtonOptimizer.h.

Constructor & Destructor Documentation

gtsam::GaussNewtonOptimizer::GaussNewtonOptimizer	(	const NonlinearFactorGraph &	graph,
		const Values &	initialValues,
		const GaussNewtonParams &	params = `GaussNewtonParams()`
	)

Standard constructor, requires a nonlinear factor graph, initial variable assignments, and optimization parameters. For convenience this version takes plain objects instead of shared pointers, but internally copies the objects.

Parameters

graph	The nonlinear factor graph to optimize
initialValues	The initial variable assignments
params	The optimization parameters

Definition at line 29 of file GaussNewtonOptimizer.cpp.
