Computing accurate singular vectors and eigenvectors using mixed-precision Jacobi algorithms
Zhengbo Zhou, Françoise Tisseur, Marcus Webb
Mixed-precision variants of the Jacobi algorithm for symmetric positive definite eigenproblems and the one-sided Jacobi algorithm for singular value decompositions have recently be…

Computing accurate eigenvalues using a mixed-precision Jacobi algorithm
Nicholas J. Higham, Françoise Tisseur, Marcus Webb +1
We provide a rounding error analysis of a mixed-precision preconditioned Jacobi algorithm, which uses low precision to compute the preconditioner, applies it at high precision (amo…

Min-Max Elementwise Backward Error for Roots of Polynomials and a Corresponding Backward Stable Root Finder
Francoise Tisseur, Marc Van Barel
A new measure called min-max elementwise backward error is introduced for approximate roots of scalar polynomials . Compared with the elementwise relative backward error, thi…
