Factorization approach to structured low-rank approximation with applications

Mariya Ishteva, Konstantin Usevich, Ivan Markovsky

We consider the problem of approximating an affinely structured matrix, for example a Hankel matrix, by a low-rank matrix with the same structure. This problem occurs in system ide…

Variable projection methods for approximate (greatest) common divisor computations

Konstantin Usevich, Ivan Markovsky

We consider the problem of finding for a given -tuple of polynomials (real or complex) the closest -tuple that has a common divisor of degree at least . Extended weighted…
