Description

Connected components of an undirected graph from its adjacency matrix.

Usage

concomFromMatAdj(M)

Arguments

adjacency matrix; it must be a square symmetric matrix with numeric or Boolean entries, whose non-zero or TRUE entries indicate the connections (connection between i-th vertex and j-th vertex if the entry is located at row i and column j)

Value

The output is the same as the one of the concom function.

Examples

matAdj <- rbind(
  c(0, 1, 0, 0),
  c(1, 0, 0, 0),
  c(0, 0, 0, 0),
  c(0, 0, 0, 1)
)
