Classifications of Recurrence Relations via Subclasses of (,, ,)-quasiseparable Matrices,, are classical. In a recent paper we observed that tridiagonal matrices and unitary Hessenberg matrices both belong to a wider class of .-quasiseparable matrices and derived a complete characterization of the latter class via polynomials satisfying certain EGO-type recurrence relations. We also est

A Framelet-Based Algorithm for Video Enhancement, a framelet-based algorithm to enhance the resolution of any frames in a video clip by solving it as a super-resolution image reconstruction problem. In this paper, we extend the algorithm to video enhancement, where we compose a high-resolution video from a low-resolution one. An experimental resul

On Symmetric and Skew-Symmetric Solutions to a Procrustes Problem, matrix theory for efficient tools, we obtained the explicit analytical expressions of the optimal approximation solutions for the symmetric and skew-symmetric least-squares problems of the linear matrix equation .. This can lead to new algorithms to solve such problems.

Some Inverse Eigenvalue and Pole Placement Problems for Linear and Quadratic Pencils,the generalized eigenvalue type and damped models lead to problems of the quadratic eigenvalue type. The matrices in these systems are typically real and symmetric and are quite highly structured. The design and stabilisation of systems modelled by these equations (eg., undamped and damped vibrating
