template<int D, typename E >

void BaseMultiEdge::constructQuadraticForm ( )

virtual

Linearizes the constraint in the edge. Makes side effect on the vertices of the graph by changing the parameter vector b and the hessian blocks ii and jj. The off diagoinal block is accesed via _hessian.

Implements g2o::OptimizableGraph::Edge.

Definition at line 37 of file base_multi_edge.h.

template<int D, typename E >

void BaseMultiEdge::linearizeOplus ( JacobianWorkspace & jacobianWorkspace )

virtual

Linearizes the constraint in the edge in the manifold space, and store the result in the given workspace

Implements g2o::OptimizableGraph::Edge.

template<int D, typename E >

void BaseMultiEdge::linearizeOplus ( )

virtual

Linearizes the oplus operator in the vertex, and stores the result in temporary variable vector _jacobianOplus

template<int D, typename E >

void BaseMultiEdge::mapHessianMemory	(	double *	d,
		int	i,
		int	j,
		bool	rowMajor
	)

virtual

maps the internal matrix to some external memory location, you need to provide the memory before calling constructQuadraticForm

Parameters

d	the memory location to which we map
i	index of the vertex i
j	index of the vertex j (j > i, upper triangular fashion)
rowMajor	if true, will write in rowMajor order to the block. Since EIGEN is columnMajor by default, this results in writing the transposed

Implements g2o::OptimizableGraph::Edge.

template<int D, typename E >

void BaseMultiEdge::resize ( size_t size )

virtual

resizes the number of vertices connected by this edge

Reimplemented from g2o::HyperGraph::Edge.
