(a) Eigenvalues (blue dots) of community matrix S = DA distributed in the complex plane, where \(\,n=400,\,\gamma =\,\)0.2, D = diag(\({N}_{i}^{\ast }\)), and \({N}_{i}^{\ast }\) are uniformly drawn from interval [0.05, 1]. Eigenvalue boundary appears as red dots, as obtained from Eq. 5 evaluated at equality. (b) Similar but with eigenvalues as yellow dots for γ = 0.2, and blue dots for γ = 0.9. The \({N}_{i}^{\ast }\) are uniformly drawn from interval [0.1, 1].
