Description Usage Arguments Details Value
Construct a generalized laplacian matrix
1 |
input |
either an affinity matrix or an igraph::graph. If class(input) == 'igraph', then an affinity matrix is computed and used. Otherwise, it is assumed that the input is an affinity matrix. |
... |
additional arguments passed to affinity_matrix if class(input) == 'igraph'. |
This function involves a matrix inversion and is therefore fairly expensive for large graphs.
a generalized laplacian matrix suitable for spectral analysis.
