Hilbert matrices
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.
