A multishift QR iteration without computation of the shifts

Autor: Augustin A. Dubrulle, Gene H. Golub

Publikováno v: Numerical Algorithms. 7:173-181

Each iteration of the multishift QR algorithm of Bai and Demmel requires the computation of a “shift vector” defined bym shifts of the origin of the spectrum that control the convergence of the process. A common choice of shifts consists of the e

Numerical methods for the migration of constant‐offset sections in homogeneous and horizontally layered media

Autor: Augustin A. Dubrulle

Publikováno v: GEOPHYSICS. 48:1195-1203

This paper describes schemes for the frequency‐domain migration of constant‐offset sections in homogeneous and horizontally layered media. Their main advantage is that individual constant‐offset sections can be processed in isolation. The basis

APL functions for precision control in floating-point computations

Autor: Augustin A. Dubrulle

Publikováno v: APL

Floating-point arithmetic[1] is the design almost universally accepted for computers dealing with so-called scientific computations. It was present in some of the earliest machines and successfully survived the controversies that followed its first i
