Properties and Applications of a Symmetric Toeplitz Matrix Generated by C + 1/C Elements

IEEE Access, 2023
Utilizing derivations for the properties of a symmetric Toeplitz matrix, we obtain analytical expressions for the performance evaluation of wireless communication systems using multiple antennas at the transmitter and/or the receiver, including those for

Eigenvectors of Tensors—A Primer [PDF]

Acta Applicandae Mathematicae, 2018
We give an introduction to the theory and to some applications of eigenvectors of tensors (in other words, invariant one-dimensional subspaces of homogeneous polynomial maps), including a review of some concepts that are useful for their discussion. The intent is to give practitioners an overview of fundamental notions, results and techniques.

A note on the eigensystem of the covariance matrix of dichotomous Guttman items

Frontiers in Psychology, 2015
We consider the sample covariance matrix for dichotomous Guttman items under a set of uniformity conditions, and obtain closed-form expressions for the eigenvalues and eigenvectors of the matrix.
