zbMATH — the first resource for mathematics

Examples
Geometry Search for the term Geometry in any field. Queries are case-independent.
Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact.
"Topological group" Phrases (multi-words) should be set in "straight quotation marks".
au: Bourbaki & ti: Algebra Search for author and title. The and-operator & is default and can be omitted.
Chebyshev | Tschebyscheff The or-operator | allows to search for Chebyshev or Tschebyscheff.
"Quasi* map*" py: 1989 The resulting documents have publication year 1989.
so: Eur* J* Mat* Soc* cc: 14 Search for publications in a particular source with a Mathematics Subject Classification code (cc) in 14.
"Partial diff* eq*" ! elliptic The not-operator ! eliminates all results containing the word elliptic.
dt: b & au: Hilbert The document type is set to books; alternatively: j for journal articles, a for book articles.
py: 2000-2015 cc: (94A | 11T) Number ranges are accepted. Terms can be grouped within (parentheses).
la: chinese Find documents in a given language. ISO 639-1 language codes can also be used.

Matrix computations. (English) Zbl 0559.65011
Oxford: North Oxford Academic; Baltimore, Maryland: The Johns Hopkins University Press. XVI, 476 p. (1983).
This is a textbook where two of the currently most active researchers in numerical linear algebra expound their subject. The primary intent is to bring the thinking of current research down to the classroom, and to choose those notions that the authors deem fruitful. As an example vector and matrix norms are used from the start, and a novel proof allows introduction of the singular value decomposition without assuming knowledge about eigenvalues. Though the authors state that their choice of subjects is personal, the book gives a rather complete coverage; the only subarea of importance at this level that has been omitted, is direct methods for sparse linear systems. Chapter headings: 1. Background matrix algebra. 2. Measuring vectors, matrices, subspaces, and linear system sensitivity. 3. Numerical matrix algebra. 4. Gaussian elimination. 5. Special linear systems. 6. Orthogonalization and least squares methods. 7. The unsymmetric eigenvalue problem. 8. The symmetric eigenvalue problem. 9. Lanczos methods. 10. Iterative methods for linear systems. 11. Functions of matrices. 12. Special topics.
