Webhilb(n) returns a Hilbert matrix with the dimension n. cond() then calculates the condition number, which is a scalar value. Currently, Matlab is returning condition as a single value using the first value from n, which is 2 instead of a vector that is equal in length to n. Webhilb. Hilbert matrix. Syntax. H = hilb(n) Description. H = hilb(n) returns the Hilbert matrix of order n. Definition. The Hilbert matrix is a notable example of a poorly conditioned matrix .The elements of the Hilbert matrices are .

Cauchy determinants[edit] The determinant of a Cauchy matrix is clearly a rational fractionin the parameters (xi){\displaystyle (x_{i})}and (yj){\displaystyle (y_{j})}.
WebJul 1, 2024 · Hankel matrices are frequently encountered in applications where the close interplay between polynomial and matrix computations is exploited in order to devise very effective numerical solution algorithms. In linear algebra, a Hilbert matrix, introduced by Hilbert (1894), is a square matrix with entries being the unit fractions $${\displaystyle H_{ij}={\frac {1}{i+j-1}}.}$$For example, this is the 5 × 5 Hilbert matrix: See more Hilbert (1894) introduced the Hilbert matrix to study the following question in approximation theory: "Assume that I = [a, b], is a real interval. Is it then possible to find a non-zero polynomial P with integer coefficients, such … See more • Hilbert, David (1894), "Ein Beitrag zur Theorie des Legendre'schen Polynoms", Acta Mathematica, 18: 155–159, doi:10.1007/BF02418278, ISSN 0001-5962, JFM 25.0817.02.
