Backward Errors for Eigenvalue and Singular Value Decompositions

, 1994
. We present bounds on the backward errors for the symmetric eigenvalue decomposition and the singular value decomposition in the two-norm and in the Frobenius norm.

Gegenbauer polynomials and semiseparable matrices

, 2007
. In this paper, we develop a new O(n log n) algorithm for converting coefficients between expansions in different families of Gegenbauer polynomials up to a finite degree n.

Spectral Factorization of Laurent Polynomials

, 1997
. We analyse the performance of five numerical methods for factoring a Laurent polynomial, which is positive on the unit circle, as the modulus squared of a real algebraic polynomial.

Splitting a matrix of Laurent polynomials with symmetry and its application to symmetric framelet filter banks

, 2008
. Let M be a 2 × 2 matrix of Laurent polynomials with real coefficients and symmetry. In this paper, we obtain a necessary and sufficient condition for the existence of four Laurent polynomials (or FIR filters) u1, u2, v1, v2 with real coefficients and ...
