Given a square matrix mat, return the sum of the matrix diagonals. Only include the sum of all the elements on the primary diagonal and all the elements on the secondary diagonal that are not part of ...
Figure 1: One-dimensional lattices with diagonal and off-diagonal disorder. In investigating these questions, optics provides a particularly useful platform to explore random matrix theory and the ...
Department of Electrical and Computer Engineering and Technology, Minnesota State University, Mankato, USA. where is a diagonal matrix of eigenvalues. Eigenvector robustness is a relatively recent ...
Abstract: Optimizing wireless propagation channels is essential for advancing future communication technologies, particularly in dynamic vehicular environments where high vehicle mobility is a ...
Add a description, image, and links to the diagonal-traversal-of-matrix topic page so that developers can more easily learn about it.
Abstract: Reconfigurable intelligent surfaces (RISs) allow controlling the propagation environment in wireless networks by tuning multiple reflecting elements. RISs have been traditionally realized ...
