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

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
