Abstract: We study the quadratic matrix equation X 2 − EX − F = 0, where E is diagonal and F is an M‐matrix. Quadratic matrix equations of this type arise in noisy Wiener–Hopf problems for Markov ...

One such example is low-rank matrix sensing under restricted isometry properties (RIP). It can be formulated as a minimization problem for a quadratic function on the Riemannian manifold of low-rank ...

Revise how to recognise and determine the equation of a quadratic function from its graph. BBC Bitesize Scotland revision for SQA National 5 Maths.

The energy term in the CEOS is a quadratic form, which is diagonalized by applying a linear transformation. The number of the reduction parameters is related to the rank of the matrix C with elements ...

In this paper, based on the factorization framework, we propose a novel robust matrix completion scheme via using the truncated-quadratic loss function, which is non-convex and non-smooth, and ...
