This book treats these four problems in a unified way. It contains not only theoretical results (based on formal orthogonal polynomials or rational interpolation) but also numerical analysis and algorithmic aspects, implementation heuristics, and polished software (the package ZEAL) that is available via the CPC Program Library. Graduate studets and researchers in numerical mathematics will find this book very readable.Lecture Notes in Mathematics,0075-8434 ;1727Functions of complex variablesNumerical analysisFunctions of a Complex Variablehttps://scigraph.springernature.com/ontologies/product-market-codes/M12074Numerical Analysishttps://scigraph.springernature.com/ontologies/product-market-codes/M14050Functions of complex variables.Numerical analysis.Functions of a Complex Variable.Numerical Analysis.51565H05msc30C15msc65E05mscKravanja Peterauthttp://id.loc.gov/vocabulary/relators/aut65497Barel Marc Vanauthttp://id.loc.gov/vocabulary/relators/autMiAaPQMiAaPQMiAaPQBOOK9910146313703321Computing the Zeros of Analytic Functions2504503UNINA
