Generate a graph Laplacian
Description
Generates a graph Laplacian from the graph adjacency matrix.
Usage
adj2lapl(A)
Arguments
A
n-by-n adjacency matrix for a graph with n nodes
Details
A graph Laplacian is defined as:
l_{i,j} = deg( v_i ) , if i = j ;
l_{i,j} = -1 , if i \neq j and v_i is adjacent to v_j;
and l_{i,j} = 0 , otherwise
Value
The n-by-n Laplacian matrix of the graph
