are 2x3, 3x2, and 2x2 matrices, respectively. The last matrix has a particularly nice structure — we say that a matrix is a square matrix if the number of rows equals the number of columns. Square matrices have many nice properties that non-square matrices do not have, such as determi...

We discuss techniques for rigorous estimations of eigenspaces and eigenvalues of a matrix. We give two kinds of results. In the first one, which is a generalization of Gerschgorin theorems, we consider blocks on the diagonal and provide bounds for eigenvectors. Second one is based on ideas ...
The conditions for a matrix to have all its eigenvalues inside an ellipse are obtained and explained in terms of a vector norm. A set of functions orthogonal on the ellipse is obtained and the relation between the Chebyshev filter and these functions is presented. The Butterworth filter is deri...
The eigenvalues of the transition matrix for random walks on a network play a significant role in the structural and dynamical aspects of the network. Nevertheless, it is still not well understood how the eigenvalues behave in small-world and scale-free networks, which describe a large variety ...
Eigenvalues[m] gives a list of the eigenvalues of the square matrix m. Eigenvalues[{m, a}] gives the generalized eigenvalues of m with respect to a. Eigenvalues[m, k] gives the first k eigenvalues of m. Eigenvalues[{m, a}, k] gives the first k generalize
Let G be a graph with adjacency matrix A(G) and let D(G) be the diagonal matrix of the degrees of G. For every real α∈[0,1], Nikiforov defined the matrix Aα(G) as Aα(G)=αD(G)+(1α)A(G). In this paper, we study the kth largest eigenvalue of Aα-matrix of grap...
