laplacian_matrix_complex function

Complex Graph Laplacian

The Laplacian of a signed graph containing ambivalent ties.

laplacian_matrix_complex(g, attr, norm = FALSE)

Arguments

• g: igraph object.
• attr: edge attribute name that encodes positive ("P"), negative ("N") and ambivalent ("A") ties.
• norm: Whether to calculate the normalized Laplacian. See definitions below.

Returns

a complex matrix

Details

See laplacian_matrix of igraph for more details. In the complex case, D is a diagonal matrix containing the absolute values of row sums of the complex adjacency matrix.
