graph.eigen {igraph} | R Documentation |
Eigenvalues and eigenvectors of the adjacency matrix of a graph
Description
graph.eigen()
was renamed to spectrum()
to create a more
consistent API.
Usage
graph.eigen(
graph,
algorithm = c("arpack", "auto", "lapack", "comp_auto", "comp_lapack", "comp_arpack"),
which = list(),
options = arpack_defaults()
)
Arguments
graph |
The input graph, can be directed or undirected. |
algorithm |
The algorithm to use. Currently only |
which |
A list to specify which eigenvalues and eigenvectors to calculate. By default the leading (i.e. largest magnitude) eigenvalue and the corresponding eigenvector is calculated. |
options |
Options for the ARPACK solver. See
