Webgraph_from_incidence_matrix can operate in two modes, depending on the multiple argument. If it is FALSE then a single edge is created for every non-zero element in the incidence matrix. If multiple is TRUE, then the matrix elements are rounded up to the closest non-negative integer to get the number of edges to create between a pair of vertices. WebNov 16, 2024 · The first n − 1 columns of the matrix form the incidence matrix of a tree, so these are linearly independent. It follows that the span of these n − 1 columns is given by the subspace S ⊂ R n, defined by S = { ( x 1, …, x n): x 1 + ⋯ + x n = 0 }.
