Function compute_degree_matrix 

pub fn compute_degree_matrix(
    adj_row_offsets: &[usize],
    num_nodes: usize,
) -> Vec<f64>

Compute the degree of each node from CSR row offsets.

degree[i] = adj_row_offsets[i+1] - adj_row_offsets[i].

Arguments

• adj_row_offsets – CSR row pointer (length num_nodes + 1).
• num_nodes – Number of nodes.
