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.

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.
