A common approach to solve problems in numerical linear algebra eeciently on modern high speed computers is to redesign the classical algorithm, which was originally developed for serial computers. In this paper, we discuss block variants of QR and Jacobi algorithms for the computation of the complete spectral decomposition of symmetric matrices. We report(More)
1995 v Acknowledgements It is my strong desire to thank all the people who have supported the present work. Above all, I am indebted to Prof. W. Gander, my supervisor, for giving me the freedom to explore new ideas and for providing a good productive environment. His algorithmic spirit and his appreciation for numerical details has become for me an ideal to(More)
