Repeat Problems 17 and 18 for the spectral densities of the Laplacian matrices.

17. Plot spectral densities of the adjacency matrices for the following networks: (i) US Air-97
and (ii) CPAN [13]. Details on these networks can be found in Section 5.3. Comment on the
types of the networks based on the shape of their spectral densities.
18. Plot spectral densities of the adjacency matrices for the following networks: (i) Diseasome [14]
and (ii) Power Grid [15]. Details on these networks can be found in Section 4.4. Comment
on the types of the networks based on the shapes of their spectral densities.

This problem is a computer-based exercise. You may use an appropriate software such Matlab
for solving this problem. Some useful code fractions can be found at the support website:
