bool VertexFinder::findVertex	(	std::vector< SimpleTrack3D > &	tracks,
		std::vector< Eigen::Matrix< float, 5, 5 > > &	covariances,
		std::vector< float > &	vertex,
		float	sigma,
		bool	fix_xy = `false`
	)

Here is the caller graph for this function:

bool VertexFinder::findVertex	(	std::vector< SimpleTrack3D > &	tracks,
		std::vector< float > &	vertex,
		float	sigma,
		bool	fix_xy = `false`
	)

The method will find the vertex given an initial guess and a list of track candidates.

Parameters

[in]	tracks	List of track candidates
[in,out]	vertex	The vertex position in x,y,z
