Laurent Polynomial Inverse Matrices and Multidimensional Perfect Reconstruction Systems
… set of invertible (resp.: noninvertible) N x P matrices. Lastly we study the generalized inverse on polynomial (resp.: Laurent polynomial) matrices.

Algorithmic enhancements to polynomial matrix factorisations
… decomposition (EVD) to parahermitian Laurent polynomial matrices - named the polynomial matrix EVD (PEVD) - has proven to be a useful tool for the decomposition of spacetime covariance matrices and their associated cross-spectral density matrices. Existing PEVD methods typically operate in the …

Mathematical modelling and optimal multivariable control of chemical processes
… domain conforming to an algebraic ring of polynomials, to eliminate the transcendental terms which arise in the Laplace domain due to the distributed nature of the plant model. This has made possible the application of linear control theories to a set of linear-partial differential …

Hybrid Symbolic-Numeric Computing in Linear and Polynomial Algebra
… methods for solving problems in linear and polynomial algebra. We mainly address the approximate GCD problem for polynomials, and problems related to parametric and polynomial matrices. For symbolic methods, our main concern is their complexity and for the numerical methods we are more …
